At least 0.1 BTC. Thanks
LOL At least 0.1 BTC. Thanks 
You expect 0.1 BTC in return for that person. isn't that too little bit.Having 50,000 BTC is of course just gibberish without proof of address or transactions that have ever been carried out.
Bought in 2010 and didn't sell until now. Does not make sense. It takes evidence to explain it's not just gibberish.
That amount of 0.1 BTC that compared to 50,000 btc is a pittance, for me it would mean a lot and it would help me a lot because as a result of the pandemic I have been left with many debts.

And I want to assume that iwoswinvs is telling the truth.
There is always hope.
On the other hand, if he has that amount of btc, it only remains to recommend that he be careful because if bad people find out that he has it, they can do something to him.
