BIT: BTC demand structure repair, ETF daily net inflow hits new high since mid January On April 21st, according to analyst Markus Thielen, the demand structure for Bitcoin is gradually being repaired. Strategy (formerly MicroStrategy) continued to increase holdings to provide stable buying support, Coinbase Premium continued to rebound, and the net inflow of spot Bitcoin ETFs reached $664 million per day, the highest level since mid January. The combination of corporate financial buying, ETF fund inflows, and US spot demand, coupled with the continuous return of stablecoin funds, has gradually strengthened liquidity support. Analysts point out that the market may be building a new oscillation range. If the above trend continues, the probability of prices moving up the range is increasing, but the market will not rise linearly.
