Further showcasing the growing accumulation pattern, Bitcoin inflows to accumulation addresses hit a new all-time high of 25,300 BTC on March 22, according to an X post by verified CryptoQuant author IT Tech.

This suggests that big investors are likely betting on more upside after the recent 15%–20% drawdown from the all-time high of around $74,000.
