Yeah, me neither. I really doubt that he has 800 Bitcoin. He wouldn't be asking us that question, he would have a consultant or something.
If he really has 800BTC, I'm sure it didn't come out of nowhere, neither he bought 800BTC. He might have done some business or whatever and should already knows how to use it and what to do with it if it is true.
He wouldn't be here asking for random opinions or advices when he could hire a advisor for himself.
Looks more like a bullshit to me

Yes i agree with you. Better do business in real life than online if you have 800 bitcoins and if he loaning his 800 bitcoins, that is very2 risky way to do.
