A Cardano (ADA) é uma plataforma criada em 2015 por Charles Hoskinson, co-fundador da Ethereum, e possui um projeto bastante ambicioso. Sua intenção é unir as melhores características e funcionalidades de todas as mais de 2 mil criptomoedas existentes no mundo, resolvendo problemas e oferecendo novas soluções para as moedas digitais.
O projeto é definido como a terceira geração de criptomoedas. Neste raciocínio, o Bitcoin seria a primeira geração, o Ethereum a segunda, e a Cardano a terceira geração.
Um dos principais objetivos da Cardano é, usando um blockchain, ser uma moeda digital, assim como o Bitcoin. A ideia é servir como um meio de pagamento alternativo em países que dificuldade de acesso a bancos. Para isso, um de seus focos é melhorar a velocidade com que as transações são feitas.
Além disso, a Cardano foi a primeira criptomoeda baseada em uma metodologia científica. Isso trás mais força para seu código, que é avaliado e revisado por uma grande equipe de pesquisadores, cientistas, engenheiros e desenvolvedores
The founder of Cardano, Charles Hoskinson, reaffirms his conviction that the biggest competitor to Bitcoin's dominance is not another project, but Cardano itself. According to him, the platform has evolved consistently over the last seven years, maintaining a focus on decentralization, security, and a solid monetary policy — aspects that, in his view, surpass the historical limitations of Bitcoin.
Hoskinson highlights innovations such as the Extended UTXO model, which expands the basic structure of Bitcoin and allows for the creation of smart contracts while maintaining the security of the network. Additionally, the on-chain governance system and the Plutus programming language are pointed out as differentiators that, according to him, realize ideas initially discussed in the Bitcoin ecosystem but never implemented.
Another emphasized point is the operational stability of the Cardano network, which has been running for seven years without interruptions, attacks, or serious failures, using a proof-of-stake model that, besides being more energy-efficient, offers security comparable to that of Bitcoin's proof-of-work.
Despite this positive technical history, Hoskinson does not ignore the growing institutional interest in Bitcoin, driven by major players like BlackRock, which already holds over 600,000 bitcoins. He acknowledges that, with institutional support and recent technological advancements like the Taproot upgrade, Bitcoin has expanded its presence in the DeFi market. Still, he envisions a future where Bitcoin could reach values between US$ 250 million and US$ 1 million, but believes that Cardano offers a more prepared architecture for the complexities of the sector.

Bitcoin (BTC) is in decline after once again hitting strong resistance at the level of $110,000. In the geopolitical environment, rising tensions in the Middle East are harming the performance of risk assets. Yesterday, the United States began to evacuate its embassy in Iraq and authorized other non-essential personnel to leave other countries in the region due to the risk of an attack by Israel on Iran.
Around 10:38 AM (Brasilia time), Bitcoin is down 2.5% in 24 hours, quoted at $106,912, and Ether, the digital currency of the Ethereum network, is down 2.1% at $2,742, according to data from CoinGecko. The total market value of all cryptocurrencies in the world is currently $3.49 trillion. In Brazilian reais, Bitcoin shows a depreciation of 2.6% at R$599,032, according to values provided by Cointrader Monitor.
Among the altcoins, XRP, the international payment token from Ripple, is down 3.5% at $2.24. Solana records losses of 4.8% at $158.30, and BNB (token of the Binance Smart Chain) declines by 0.9% to $661.48
The proxy conflict dates back to the Iranian Revolution, where Iran became an Islamic republic. Iranian Islamic revolutionaries specifically called for the overthrow of the monarchies in the region and their replacement with Islamic republics, which alarmed their Sunni Arab neighbors such as Iraq, Saudi Arabia, Kuwait, and the other Gulf States – most of which were monarchies and all had considerable Shiite populations. Islamist insurgents would emerge and rebel in Saudi Arabia (1979), Egypt (1981), Syria (1982), and Lebanon (1983).
Before the Iranian revolution, the two countries constituted the policy of Nixon's Doctrine of the "twin pillar" in the Middle East. The monarchies, particularly Iran, allied with the United States to ensure stability in the Gulf region and act as a bulwark against Soviet influence during the Arab Cold War. The alliance acted as a moderating influence on Saudi-Iranian rivalry. By that time, the Kingdom of Saudi Arabia had oil wealth and prestige as the land of Mecca and Medina, the two holy cities of Islam. By utilizing Islam, Saudi Arabia sponsored an international Islamic conference in Mecca in 1962. It created the Muslim World League, dedicated to spreading Islam and promoting Islamic solidarity. The League was "extremely effective" in promoting Islam, particularly conservative Wahhabi Islam in the Muslim world. Saudi Arabia also led the creation of the Organization of Islamic Cooperation in 1969.
Michael Saylor rejected recent criticisms from a legendary short seller during an interview with Bloomberg TV on Tuesday, explaining his company's business model and his perspective on the future of Bitcoin.
In response to Jim Chanos' short-selling recommendation on MicroStrategy's stock, Saylor stated: "I don't think he understands what our business model is. We are the largest issuer of Bitcoin-backed credit instruments in the world."
$BTC Chegou perto, mas não foi o suficiente. Após conversas entre os governos dos Estados Unidos e da China, o mercado de criptomoedas ganhou fôlego, e o bitcoin (BTC) chegou a marcar US$ 110.561, segundo o Coin Market Cap, cerca de 1,2% abaixo de sua máxima histórica.
Nesta terça-feira (10), por volta das 14h, o BTC recuou levemente em relação ao dia anterior e era negociado a cerca de US$ 109 mil — uma alta de 8,1% em relação à última sexta-feira (6), quando a criptomoeda quase caiu abaixo dos US$ 100 mil, atingindo o menor valor nos últimos 30 dias. O movimento positivo também arrastou para cima algumas das maiores altcoins do mercado.
The tariffs during Donald Trump's second presidency reflected an escalation of protectionist trade policies in the United States under Donald Trump. While in his first term he imposed tariffs on approximately 380 billion dollars in imports, the total for his second administration is expected to exceed 1.4 billion dollars by April 2025.[1]
In his second term, Trump resumed a trade war with China and launched a second trade war with Canada and Mexico, framing these actions as a way to hold these countries accountable for drug trafficking and illegal immigration, while also supporting domestic production.[2][3] On March 4, 2025, he increased tariffs on all Chinese imports to 20%. He also imposed a 25% tariff on most Canadian and Mexican products but later exempted all products in accordance with the USMCA. On March 12, 2025, a global tariff of 25% on steel and aluminum products came into effect.

Today's roundtable is titled "DeFi and the American Spirit." This is an appropriate title because American values of economic freedom, private property rights, and innovation are in the DNA of the DeFi movement, or Decentralized Finance.
Blockchains, of course, are a very creative and potentially revolutionary innovation that makes us rethink the proof of ownership and the transfer of intellectual and economic property rights. They are shared databases that allow ownership of a type of digital property called crypto-assets without dependence on an intermediary or central authority. Instead, these peer-to-peer networks incorporate an economic mechanism to incentivize participants to validate and maintain the database according to the rules of the network. They are free market systems where users pay fees based on demand to network participants for their transactions to be included in a so-called "block" of data with finite storage capacity.

subiu 3,5% entre 7 e 9 de junho, se aproximando da marca de US$ 108.500. Apesar dessa recente alta, traders profissionais permanecem notavelmente cautelosos, como reflete as métricas de derivativos do BTC. Tensões macroeconômicas mais amplas persistem, e o Bitcoin continua mostrando uma forte correlação com o mercado de ações, limitando seu potencial de alta no curto prazo.
Alguns analistas antecipam que o Bitcoin possa subir para US$ 150.000 à medida que o governo dos EUA se aproxima de um aumento de US$ 4 trilhões no teto da dívida. No entanto, os dados do mercado de futuros sugerem hesitação no curto prazo, provavelmente impulsionada por sinais macroeconômicos desfavoráveis e uma leitura equivocada do potencial choque de oferta do Bitcoin.
In finance and economics, a recovery refers to the rebound from a previous period of negative activity or losses — such as a company that reports solid results after a year of losses or launches a successful product line after facing difficulties with false starts.
Investing.com — Robert Kiyosaki, author of the book "Rich Dad Poor Dad" and known for his unorthodox views on the financial system, has drawn attention again on social media following recent strong statements. In light of increasing internal tensions in the United States and global instability, he warned of systemic risks in the financial structures. While commenting on the episodes of violence following ICE operations in Los Angeles, the author used the phrase "the civil war has begun," projecting a long, hot summer marked by confrontations, both in the U.S. and in other parts of the world.
Kiyosaki linked the current social unrest to the theory of the "Fourth Turning," developed by Strauss and Howe, which proposes that approximately every 80 years, societies go through major upheavals. Historical examples such as the Great Depression, the American Civil War, and the American Revolution are cited as previous milestones, and Kiyosaki sees current events as a harbinger of a new structural transition.
NEW YORK, May 16 (Reuters) - The market's momentum following the trade truce between the United States and China has brought stocks back into the spotlight of historical highs, but caution regarding the economic consequences of remaining tariffs and higher stock valuations may slow gains in the short term.
The S&P 500 (.SPX) has risen 18% since it hit its lowest closing point of the year on April 8, erasing the benchmark index's losses for 2025 and placing it about 4% from its historical peak reached in February.

Bitcoin (BTC) is known as the first open-source, peer-to-peer cryptocurrency, developed and launched by a group of unknown independent programmers called 'Satoshi Nakamoto' in 2008. Bitcoin has no centralized server for its issuance, transactions, and storage, as it uses a public database technology, a distributed network called blockchain, which requires an electronic signature and is supported by a proof-of-work protocol to provide the security and legitimacy of transactions. The issuance of Bitcoin is done by users with mining capabilities and is limited to 21 million coins. Currently, the market value of Bitcoin exceeds $200 billion, and this is the most popular type of digital currency. Buying and selling cryptocurrencies is available through Bitcoin exchanges or ATMs.
