Bitcoin ETFs have seen inflows of over $2 billion, driven by institutional interest and a bullish market sentiment as Bitcoin nears $70,000. BlackRock's ETF has been a major contributor to these gains, reflecting increased confidence in Bitcoin as an asset. On the other hand, Ethereum funds have experienced a day of outflows, highlighting a divergence in market sentiment between the two major cryptocurrencies. Ethereum is facing challenges from competing Layer-2 solutions, which may be impacting investor confidence in its long-term growth potential.
