The most 'powerful' or dominant cryptocurrency today is Bitcoin (BTC). With an approximate price of 105,175 USD and a market capitalization exceeding 2 trillion dollars (≈ 63% of the total market), Bitcoin maintains its supremacy as the benchmark of the sector. Its network is the most secure, decentralized, and has a limited supply (21 million coins), which reinforces its value as a 'digital reserve'. Although others like Ethereum (≈ 2,541 USD, ~9% of the market) offer advanced functionalities (smart contracts, dApps), none surpass the influence or economic weight of Bitcoin in the current crypto ecosystem.
