Jason Calacanis, a prominent Silicon Valley angel investor, has expressed concerns via Twitter that if MicroStrategy (MSTR) continues to accumulate excessive amounts of Bitcoin (BTC), it could destabilize the cryptocurrency market. Calacanis suggests that an individual or entity holding a significant portion of the BTC supply disrupts the perceived fairness of the game. As of this writing, MicroStrategy holds 444,262 BTC (worth approximately $43.27 billion) at an average price of $62,351 per coin, representing about 2.11% of the total BTC in circulation. Calacanis believes that if MicroStrategy's holdings approach 10% of the supply, it could trigger a shift in investor sentiment, leading them to seek alternative investment opportunities that offer a more equitable distribution of ownership.
