Bitcoin's price has surged above $63,000 as investor concerns over potential government Bitcoin sales and the threat from Mt. Gox began to dissipate. The rise in price is accompanied by significant activity in Bitcoin ETFs, with net inflows recorded for five consecutive days. BlackRock has been a prominent buyer, continuing to purchase Bitcoin despite a recent 15% drop in price. Bitcoin ETFs collectively bought 2,050 BTC worth $129 million, with inflows hitting a monthly high of $129.45 million. Fidelity led the inflows with $65 million, marking the largest inflow since June 7.
