That's a mistake made by your friend.
Why would he buy an NFT without doing any research about it? He should've done better for himself and didn't just bought without knowing what's with the NFT he bought.
Sorry for your friend but that's a lesson to be learned.
Lesson from a tough, experienced, investing without doing further research most of the time ends up like this,
if you wanted to invest, you need to spare more time in studying the business, sorry for that person he can no
longer turned back the time but he can use that mistake to avoid losing more money when investing, if he choose
to continue, he should take deeper investigation before throwing his money.
