According to @AltcoinGordon, Bitcoin's (BTC) recent rally to a new all-time high has pushed its market dominance above 54%, while major altcoins like Ethereum (ETH) and Solana (SOL) lag significantly behind their own peaks, based on analysis from Lionsoul Global. Historically, altcoin rallies have followed Bitcoin's all-time highs with a delay of two to six months, suggesting a capital rotation into altcoins could be on the horizon, as noted by Gregory Mall. Early signs of this shift may include ETH's recent 81% rally from its April lows and a resurgence in DeFi, with total value locked (TVL) now exceeding $117 billion, according to DeFiLlama data. Institutional demand provides a strong tailwind, with analysis from Kevin Tam indicating that spot Bitcoin ETF purchases over the last year were three times higher than the network's new supply. However, a recent OECD report highlights the fragility of the global economy, reminding traders that cryptocurrencies remain a risk-on asset class.
