ARK Invest sold a significant block of its own ARK 21Shares Bitcoin ETF shares on Monday following the fund's strong month, which is a notable move from an issuer that has been among the most vocal Bitcoin advocates. Strive went the other direction, adding 469 BTC to reach 25,000 in total holdings. The split between a fund manager trimming and a treasury company accumulating is the cleanest illustration of how differently the two sides read this level.
