Hello
after 12 years i remember i bought bitcoin in 2010
is it possible to sell more than 50,000 bitcoins at once or is it better to sell direct to a private individual like grayscale or microstrategy?
damn that's a lot of Funds , 50,000 Bitcoin ? So you're one of the early adopter and one of the person that becomes Billionaire .
Never put all eggs in single transaction , better put at least 5,000 per transaction , You are a very lucky person mate and hope you'll use the funds in a right way .
