VanEck and WisdomTree's Bitcoin ETFs experienced a significant surge in trading volume, leaving analysts puzzled about the sudden uptick. VanEck's "HODL" fund saw its trading volume spike to $258 million on Feb. 20, a nearly 15-fold increase from the previous day. This surge was driven by approximately 32,000 individual trades, a stark contrast to its average volume. The reason behind this sudden increase remains unclear. Analysts speculate that it could be related to a recommendation from a social media influencer on platforms like Reddit or TikTok, given the exponential rise in the number of trades. This speculation aligns with the current trend of retail investors influencing market movements.
