There's been quite noticeable activity on the BTC options side.

Even though short-term panic hedging hasn't completely faded right now, some funds are starting to position in bullish call options.
Starting from late March and into April, there's been significant buying of 75,000 call options, and what's more interesting is that part of these funds chose to sell put options below 60,000 to finance the purchase of call options.
Additionally, for BTC options expiring in March, bullish calls are around $660 million while put options are roughly $240 million, with a ratio close to 3:1.
Capital flow data doesn't lie—the market has already seen a considerable amount of capital beginning to shift from bearish to bullish positions.
