$BTC By June 2025, some currency pairs with BTC that could take the spotlight include: BTC/USDT, the classic stable haven; BTC/ETH, ideal for measuring the pulse of the crypto market; and BTC/USDC, increasingly popular due to its clear regulation. Greater activity is also expected in pairs like BTC/EUR and BTC/JPY due to the growth of global institutional interest. In riskier markets, pairs like BTC/SOL or BTC/ORDI could offer attractive volatility for traders. In summary, BTC will remain king, and its value against stablecoins, fiat, and altcoins will reflect both the health of the market and the sentiment of investors.
