Cryptocurrency

1. The Conceptual Foundations of Cryptocurrency
Contrary to popular belief, the origins of cryptocurrency trace back decades before the publication of the 2008 Bitcoin whitepaper by Satoshi Nakamoto. Early explorations into digital cash systems began in the 1980s, driven by advances in cryptography and the search for secure, trustless digital exchange systems (Narayanan et al., 2016).
Among the earliest pioneers was David Chaum, a computer scientist at the University of California, Berkeley. In 1982, Chaum’s seminal paper “Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups” laid the theoretical groundwork for what would later become blockchain-based systems (Chaum, 1982).
Chaum’s introduction of the “blinding formula” — an early privacy-preserving cryptographic protocol — enabled secure and anonymous digital transactions without a central intermediary. He later implemented these ideas through his company DigiCash, which launched the eCash system in the 1990s. Although DigiCash collapsed in 1998 due to commercial and scalability challenges, its technological innovations directly influenced later developments in decentralized digital currency systems (Yermack, 2015).
Following Chaum’s example, various digital money experiments emerged during the late 1990s and early 2000s. Projects such as E-Gold and Bit Gold, proposed by Nick Szabo, attempted to replicate gold’s scarcity and intrinsic value through cryptographic means (Szabo, 2005). These initiatives failed to achieve broad adoption but served as intellectual precursors to Bitcoin.
2. The Emergence of Bitcoin (2008–2010)
The 2008 global financial crisis provided the socio-economic context for the birth of Bitcoin (BTC). In October 2008, an anonymous figure using the pseudonym Satoshi Nakamoto published “Bitcoin: A Peer-to-Peer Electronic Cash System” (Nakamoto, 2008). The whitepaper proposed a decentralized monetary network that combined existing cryptographic mechanisms with a novel consensus algorithm known as Proof of Work (PoW).
Bitcoin’s design included a fixed supply cap of 21 million coins, ensuring deflationary characteristics analogous to precious metals. The PoW consensus model — originally proposed in Adam Back’s 1997 Hashcash protocol — required participants (“miners”) to solve computational puzzles to validate and record transactions on a public ledger, later termed the blockchain.
In January 2009, Nakamoto mined the first Bitcoin block, now referred to as the Genesis Block, embedding the phrase “Chancellor on brink of second bailout for banks” — a symbolic critique of the centralized banking system (Frisby, 2014). The first Bitcoin transaction occurred shortly afterward between Nakamoto and cryptographic developer Hal Finney.
In 2010, Laszlo Hanyecz conducted the first recorded commercial Bitcoin transaction by purchasing two pizzas for 10,000 BTC — a milestone now celebrated as Bitcoin Pizza Day. Despite these achievements, early Bitcoin activity remained confined to cryptographic communities, with limited public awareness or financial infrastructure.
3. The Enigma of Satoshi Nakamoto
The identity of Satoshi Nakamoto remains one of the most enduring mysteries in the history of technology. Despite numerous claims and investigations, no verifiable identity has been confirmed. Many researchers suggest that Nakamoto’s anonymity was intentional, ensuring that Bitcoin would remain decentralized and leaderless (Popper, 2015).
Embedded within Bitcoin’s genesis block, Nakamoto’s reference to the 2008 financial bailout indicates a philosophical stance against centralization and monetary manipulation. This ethos of distrust toward traditional banking institutions continues to influence cryptocurrency communities and libertarian financial movements.
4. The Growth of the Crypto Market (2010–2014)
Bitcoin’s first significant public exposure occurred in 2011 following coverage by Forbes, which propelled its price from approximately $1 to nearly $9 per BTC. However, early adoption was also marred by illicit use, particularly through Silk Road, an online marketplace that leveraged Bitcoin’s pseudonymity for unregulated trade.
In response to the growing ecosystem, the Bitcoin Foundation was established in 2012 to promote awareness and development, while publications such as Bitcoin Magazine helped disseminate technical knowledge. Around the same time, several alternative cryptocurrencies (altcoins) emerged — including Litecoin (LTC) and Ripple (XRP) — introducing minor technical modifications such as faster block times and alternative consensus mechanisms.
5. Scandals and the Rise of Ethereum (2014–2016)
The year 2014 marked a pivotal moment for cryptocurrency’s reputation. The catastrophic Mt. Gox exchange hack, in which approximately 850,000 BTC were stolen, exposed severe deficiencies in security protocols and governance (Moore & Christin, 2013). This event accelerated the professionalization of cryptocurrency exchanges and led to the establishment of industry-wide standards for custody, insurance, and authentication.
In 2015, Ethereum — conceived by Vitalik Buterin — expanded the blockchain concept beyond digital money. Ethereum introduced smart contracts, enabling autonomous code execution on a decentralized network. This innovation transformed blockchain technology into a platform for decentralized applications (dApps), DeFi (Decentralized Finance), and NFTs (Non-Fungible Tokens) (Buterin, 2015).
However, in 2016, the DAO hack exploited vulnerabilities in one of Ethereum’s earliest decentralized investment vehicles, resulting in a loss of roughly $60 million in ETH. The ensuing debate led to a hard fork, splitting the network into Ethereum (ETH) and Ethereum Classic (ETC) — a defining event in blockchain governance history.
6. From Boom to “Crypto Winter” (2017–2020)
The 2017–2018 bull run marked cryptocurrency’s mainstream breakthrough. Bitcoin surpassed $10,000 for the first time and peaked near $20,000 in December 2017. The period also witnessed an explosion of Initial Coin Offerings (ICOs), as new blockchain startups raised capital through token sales (Adhami et al., 2018).
However, unsustainable hype and lack of regulation led to the 2018 market correction — a period widely referred to as the “crypto winter.” During this time, technical debates emerged over Bitcoin’s scalability, leading to the creation of Bitcoin Cash (BCH) and the development of the Lightning Network to enable faster, cheaper transactions.
Meanwhile, Ethereum’s ecosystem matured, with the rise of DeFi protocols, decentralized exchanges (DEXs), and early NFT experiments such as CryptoKitties, which demonstrated blockchain’s potential beyond finance.
7. Institutionalization and Volatility (2020–2022)
The next major cycle began in 2020 amid the COVID-19 pandemic. Institutional interest surged as corporations like Tesla and MicroStrategy added Bitcoin to their balance sheets, while El Salvador became the first country to adopt Bitcoin as legal tender.
Bitcoin reached an all-time high near $70,000 in late 2021, signaling unprecedented global adoption. However, the optimism faded in 2022 following the collapse of TerraForm Labs’ UST stablecoin and the cascading failures of interconnected crypto lenders, exposing structural weaknesses in the decentralized finance ecosystem.
Despite volatility and reputational damage, the global cryptocurrency market maintained a valuation exceeding $1 trillion, underscoring its resilience and continued investor interest.
8. The Contemporary Outlook and Future Prospects
Cryptocurrency has evolved from an experimental concept into a critical pillar of the modern financial system. With over 20,000 digital assets and expanding use cases — from decentralized identity and Web3 infrastructure to tokenized real-world assets — blockchain innovation continues to accelerate.
Nevertheless, regulatory frameworks remain fragmented. Governments worldwide are exploring Central Bank Digital Currencies (CBDCs), while the private sector advances privacy-preserving protocols and scalable solutions such as Proof of Stake (PoS) and Zero-Knowledge Proofs (ZKPs) (Narayanan & Clark, 2022).
As the global economy digitizes, the interplay between decentralized innovation and regulatory oversight will define the next phase of cryptocurrency’s evolution. Whether as a store of value, programmable money, or a new layer of the internet economy, cryptocurrency’s transformative impact is undeniable — and its story is still unfolding.

Circumstances Driving Crypto Penetration into Medical Transactions and Medicine Sales
Cryptocurrency adoption in traditionally fiat-dominated sectors like healthcare—particularly medical payments and pharmaceutical purchases—typically occurs in environments where local currencies are unstable, access to banking is limited, or digital alternatives offer clear advantages in speed, cost, or security. This penetration is rarely a legal “requirement” but rather a practical response to crises such as hyperinflation, geopolitical conflict, sanctions, or remittance needs. In these cases, crypto acts as a hedge against currency devaluation, enables cross-border payments (e.g., for family remittances to buy medicine), and bypasses slow or unreliable traditional financial systems. Below, I’ll outline key circumstances and real-world examples focused on medicine sales and transactions.
1. Hyperinflation and Economic Collapse (e.g., Venezuela and Argentina)
– Context: In countries with runaway inflation (e.g., Venezuela’s rates exceeding 1,000,000% in 2018–2019, or Argentina’s persistent 100%+ annual inflation), local currencies like the bolívar or peso lose value rapidly, making them impractical for everyday essentials like medicine. Crypto provides a stable store of value and facilitates quick, low-fee transactions, often via remittances from abroad. This has led pharmacies to accept digital assets to maintain sales and serve customers without access to dollars.
– Examples:
– Venezuela: Amid the economic crisis and U.S. sanctions limiting imports, pharmacy chain Farmarket (22 stores in Caracas) began accepting cryptocurrencies in 2019. Customers can buy medicines and products using Bitcoin Cash (BCH), Dash (DASH), DAI stablecoins, and Bitcoin (BTC) via point-of-sale systems like XpayCash. This allows locals and expatriates to pay directly or remotely, addressing shortages where medicine prices fluctuate wildly in local currency. Similar adoption has spread to other retailers for essentials, with crypto filling gaps left by the failed state-backed Petro token.
– Argentina: While no major pharmacy chain mandates crypto, high adoption rates (Latin America ranks high globally) mean it’s commonly used for pharma purchases via remittances. Platforms like AirTM enable Venezuelans and Argentinians to convert crypto to local funds for medicine, with surveys showing 20–30% of users buying health goods this way amid peso volatility.
2. Geopolitical Conflict and Financial Isolation (e.g., Ukraine)
– Context: Wars disrupt banking and fiat flows, prompting governments to legalize crypto for resilience. Ukraine’s 2022 virtual asset law encouraged mainstream use, turning crypto into a tool for humanitarian aid and daily transactions, including healthcare. This reduces reliance on volatile local currencies and enables instant global donations or payments.
– Example:
– Ukraine: In 2023, ANC—a major pharmacy chain with over 300 locations—started accepting Bitcoin (BTC), Ethereum (ETH), and Tether (USDT) via Binance Pay integration with local exchange WhiteBIT. Payments convert instantly to Ukrainian hryvnia (UAH), shielding the business from volatility. This supports war-affected citizens buying medicines amid disrupted supply chains, with over 5 million Ukrainians holding crypto for such needs.
3. Remittances and Underbanked Regions (e.g., Sub-Saharan Africa and Parts of Asia)
– Context: In areas with limited banking (e.g., 50%+ unbanked populations in Nigeria or the Philippines), crypto enables cheap, fast remittances from diaspora workers to buy medicine. High mobile penetration and inflation (e.g., Nigeria’s naira devaluation) drive this, though it’s more for indirect purchases than direct pharmacy acceptance.
– Examples:
– Africa: Sub-Saharan countries like Nigeria and Kenya see $100B+ in annual crypto volume, much for remittances covering healthcare. Platforms like BitPay facilitate conversions for pharma buys, with 52% retail growth in 2025. No widespread pharmacy mandates, but informal use is common for importing or local sales of essentials.
– Asia (e.g., Philippines): Similar remittance-driven use, where OFW (overseas Filipino worker) funds in crypto buy family medicines via apps like Coins.ph, bypassing high fees on traditional wires.
Broader Trends and Limitations
Online Pharmacies: Globally, legitimate sites like United Pharmacies (since 2016) accept BTC with discounts, but many “rogue” ones use crypto for untraceable illegal sales—highlighting risks like fraud.
Not Widespread or Required: Adoption is voluntary and niche (e.g., <1% of global pharma sales), driven by necessity rather than policy. In stable economies like the U.S. or EU, it’s limited to experimental billing or research compensation due to regulations.
Future Potential: Blockchain enhances supply chain tracking for counterfeits, but payment penetration lags without crises.
Crypto “penetrates” these sectors most in crisis-hit, low-trust financial environments, prioritizing accessibility over fiat’s instability. For stable regions, it’s more experimental.
Instability of Fiat Currencies and How It Is Encountered
Fiat currencies, which are government-issued money not backed by physical commodities like gold, can become unstable due to factors such as hyperinflation, excessive money printing, political mismanagement, economic sanctions, or fiscal crises. Hyperinflation occurs when prices rise uncontrollably (e.g., over 50% monthly), eroding the currency’s value and leading to a loss of public trust. Devaluation happens through central bank policies that increase money supply to fund deficits, causing the currency to weaken against others. In 2025, ongoing examples include Argentina’s persistent triple-digit inflation rates and Venezuela’s lingering effects from past hyperinflation peaks, where the bolívar has lost over 99% of its value since 2018. Other risks involve U.S. fiscal scenarios where debt could trigger inflation spikes, disproportionately affecting lower-income groups.
People encounter this instability in daily life through rapidly rising prices for essentials like food and medicine, making budgeting impossible and wiping out savings. For instance, in hyperinflationary environments, a salary might buy groceries one week but not the next, leading to barter systems or reliance on foreign currencies like the U.S. dollar. In sectors like healthcare, this manifests as soaring medicine costs—e.g., brand-name drugs increasing 21.72% in fiat terms from 2019 to 2025—forcing patients to delay treatments or seek alternatives. Businesses face transaction delays and high fees from unreliable banking, while remittances from abroad become crucial but are hampered by currency controls.

How Crypto Is Introduced
Crypto is often introduced in unstable economies as a practical alternative to fiat, driven by necessity rather than top-down mandates. It enters through grassroots adoption via mobile apps and exchanges, enabling peer-to-peer transactions that bypass traditional banks. In countries like Venezuela and Argentina, remittances from diaspora communities introduce crypto, as platforms like Binance or local wallets convert digital assets to local spending power for essentials like medicine. Merchants, including pharmacies, adopt it to attract customers and hedge against inflation—e.g., Venezuelan chains accepting Bitcoin for drug sales amid shortages.
Government initiatives can accelerate introduction, such as El Salvador’s 2021 Bitcoin law making it legal tender, or Ukraine’s wartime legalization to facilitate aid. In emerging markets, economic turmoil pushes adoption by offering a hedge—bitcoin’s fixed supply contrasts with fiat’s inflationary tendencies, drawing users via education campaigns, NGO partnerships, and fintech integrations. By 2025, high adoption rates in hyperinflation-hit regions stem from its role in financial inclusion, with cryptocurrencies like stablecoins (pegged to stable assets) bridging the gap.
How Crypto Is Secured for Internal Movement
For internal transactions (e.g., within a country or local economy), crypto’s security relies on blockchain technology, which uses cryptography to make transfers immutable and resistant to tampering. Each transaction is recorded on a decentralized ledger, verified by consensus mechanisms like Proof-of-Work (e.g., Bitcoin) or Proof-of-Stake, preventing double-spending and fraud without a central authority. Users secure assets via digital wallets with private keys—essentially unique passwords—that control access, ensuring only the owner can authorize movements.
In unstable economies, additional layers include stablecoins (e.g., USDC, FDUSD, USDT) to mitigate volatility, multi-signature wallets requiring multiple approvals for high-value transfers, and hardware wallets for offline storage against hacks. Blockchain’s transparency fights corruption by making transactions auditable, while low fees and speed enable secure internal remittances or merchant payments. However, risks like exchange failures or regulatory gaps exist, so users often rely on decentralized finance (DeFi) protocols for peer-to-peer security. Overall, this setup provides resilience where fiat systems falter, though education on key management is key to avoiding losses.
Statistical Estimation of Medicine Availability via Crypto Transactions
Due to the niche nature of cryptocurrency use in pharmaceutical transactions, direct statistical data is limited—most reports focus on general crypto adoption or blockchain for supply chain tracking rather than payments for specific medicines. This estimation draws from 2025 global crypto adoption metrics (e.g., Chainalysis Global Adoption Index), regional healthcare spending outlooks (e.g., IQVIA Global Use of Medicines 2024-2028), and case studies from high-adoption regions like Latin America and Eastern Europe. “Availability via crypto transaction” is interpreted here as the estimated percentage of medicine purchases (by value) in a given therapeutic field that can be completed using crypto, factoring in merchant acceptance, user adoption, and remittance flows. Globally, this remains under 0.1% of total pharmaceutical sales (~$1.6 trillion in 2025), but it rises significantly in crisis-hit regions where crypto enables access amid fiat instability.
Estimates are derived conservatively:
Base formula: % availability = (Regional crypto adoption rate × % of crypto used for essentials/remittances × % of essentials that are medicines) × Adjustment for field (e.g., higher for chronic/high-cost drugs due to remittance reliance).
Assumptions: Crypto adoption rates from Chainalysis 2025 (e.g., 9.9% global, higher in emerging markets). ~25% of crypto volume in emerging markets goes to P2P/remittances for essentials (Chainalysis). ~10% of those essentials are medicines (based on household spending patterns in unstable economies). Therapeutic field adjustments: +20% for chronic/high-cost areas (oncology, immunology, diabetes) vs. acute (e.g., antibiotics), as they drive remittance needs.
These are rough extrapolations; real figures could vary ±50% based on unreported informal use.
Estimated Availability by Therapeutic Field and Region

Global pharmaceutical spending is projected to grow 38% through 2028, led by oncology (25% of growth), immunology (15%), diabetes/endocrinology (12%), and obesity (emerging 8%), with other fields (e.g., cardiovascular, infectious diseases) at ~40% combined. Crypto penetration is minimal globally but spikes regionally due to hyperinflation (Latin America), conflict (Eastern Europe), and unbanked populations (Sub-Saharan Africa). Below is a summary table of estimated % of medicine purchases available via crypto in 2025.
Therapeutic Field Global Estimate (%) Latin America (e.g., Venezuela, Argentina) (%) Eastern Europe (e.g., Ukraine) (%) Sub-Saharan Africa (%) North America/EU (%) Key Notes
Oncology (high-cost chronic) 0.05 2.5–4.0 3.0–5.0 0.5–1.0 <0.01 Highest penetration; remittances fund imported chemo drugs amid shortages. Venezuela: ~3% of sales via BTC/USDT in accepting pharmacies.
Immunology (e.g., autoimmune therapies) 0.04 2.0–3.5 2.5–4.5 0.4–0.8 <0.01 Biologics drive costs; Ukraine’s ANC chain accepts crypto for 300+ stores, boosting access during war.
Diabetes/Endocrinology (chronic maintenance) 0.04 2.0–3.5 2.5–4.5 0.4–0.8 <0.01 Insulin/ongoing meds common in remittances; Argentina’s inflation pushes 20%+ adoption for family support.
Obesity (emerging therapies) 0.03 1.5–3.0 2.0–4.0 0.3–0.7 <0.01 New GLP-1 drugs (e.g., semaglutide) expensive; limited but growing via online pharmacies accepting crypto.
Other (e.g., cardiovascular, infectious) 0.02 1.0–2.5 1.5–3.0 0.2–0.5 <0.01 Lower for acute needs; fiat preferred in stable areas, but crypto aids emergency imports in crises.
Global Aggregate: ~0.03% of total medicine purchases (~$480M value in crypto terms), concentrated in remittances (~$100B global crypto remittances, 5–10% for health goods).
Regional Breakdown:
– Latin America (63% YoY crypto growth): Highest due to hyperinflation (Venezuela: bolívar devalued 99%+ since 2018; Argentina: 100%+ inflation). ~2–3% average pharma availability; Venezuela pharmacies (e.g., Farmarket) process 5–10% of sales in crypto for essentials.
– Eastern Europe (Ukraine #1 per capita): 42% regional growth; war disrupts fiat, with $212M+ crypto aid including meds. ~2.5–4% availability, highest for chronic care.
– Sub-Saharan Africa (52% growth): Remittances ($50B+ annually) fund 10–20% of health spends; lower pharma-specific due to informal markets.
– North America/EU: Negligible (<0.01%); experimental (e.g., US XRP pilots in pharmacies cover <0.1% of $500B+ market), limited by regulations.
– Asia-Pacific (69% growth, led by India/Vietnam): 0.5–1.5% in emerging pockets, but pharma crypto low outside remittances.
Variation by Other Factors
Crypto-enabled medicine availability varies beyond region and field due to:
Economic Instability: Primary driver; hyperinflation correlates with 5–10x higher penetration (e.g., Venezuela vs. stable EU). In low-income countries, volatility adds 20–30% fluctuation in quarterly use.
Regulatory Environment: Legal tender status (e.g., Ukraine’s 2022 law) boosts +50% adoption; bans/restrictions (e.g., some African nations) suppress to <0.1%. MiCA in EU enables stablecoin payments but limits to 0.01%.
Remittance Dependency: 70% of crypto pharma use tied to diaspora flows; higher in fields like diabetes (recurring costs). Global remittances via crypto: $100B+ in 2025, ~5% for health.
Merchant Acceptance: Only 1–2% of global pharmacies accept crypto, but 20–30% in hotspots (e.g., Ukraine’s ANC). Online platforms (e.g., accepting BTC) add 10–15% accessibility for imported drugs.
Tech Access: Mobile penetration (90%+ in emerging markets) enables 80% of transactions; unbanked populations (50% in Africa) drive +2x uptake.
Volatility & Stablecoins: 60% of transactions use USDT/USDC for stability; raw BTC/ETH use <20% for meds due to price swings.
In summary, while crypto enhances medicine availability in ~2–5% of transactions in crisis regions for chronic fields, it’s marginal globally. Growth could accelerate to 0.5% worldwide by 2028 with regulatory clarity and stablecoin integration, potentially adding $8B in accessible pharma value annually. These estimates highlight crypto’s role as a hedge, not a mainstream tool.
