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?
Only in your dreams... Anyway, that's a ridiculous question. Selling
anything worth $1.5 billion worth is going to take some effort.
I will believe OP if he posted a screenshot of his wallet, just a screenshot not wallet details, it's questionable if you bought 50000 Bitcoin and yet you do not know how to sell it, are you not reading or have have not educated yourselves on how trading works, it will take a lot of effort and time doing that it's surprising if you are really holding that amount and have not made a trade all these times.
