According to QCPgroup, altcoins experienced a sharper sell-off last week, with SOL losing nearly 20% and ETH dropping close to 10%. ETF flows failed to support prices, as BTC recorded its second-largest daily outflow and ETH saw its fourth-largest outflow on Friday. This trend suggests that recent institutional demand is not providing short-term price support, which may impact trading strategies and market sentiment for BTC, ETH, and SOL. Source: QCPgroup.

According to Milk Road (@MilkRoadDaily), a $10 billion injection into Solana (SOL) would increase its market cap by 12.8%, while the same amount added to Ethereum (ETH) would result in a 3.24% increase, and Bitcoin (BTC) would see a 0.47% rise. This analysis highlights how smaller market cap assets like SOL can experience significantly higher returns from capital inflows compared to larger assets like BTC and ETH. For traders, SOL offers higher potential upside per dollar invested, but also higher volatility, making it attractive for aggressive trading strategies.
