That is pretty nuts, but not as crazy as the guy who had roughly 20m+ on polo. Think they invested in a few BTC in stratis ico and it took off. That will take ages to get off of polo
It depends. If you don't do any verification, you can only withdraw 2000 USD a month, so thats 24000 USD a year. It would take ages to get a million ut, but if you do the verification, you can get a ton of money out, but im not sure if there is a limit.
I guess the limit is 100000 USD a day, so it would take 10 months to get a million out.
