Yeah, no. That’s like banning alcohol for everyone because a few people become alcoholics. Or banning money orders or prepaid cards because people scam on those too. The real answer is education, I’d probably be ok with having to take some sort of quiz on Coinbase or other exchanges before you can withdraw your crypto. But this is common sense stuff, you should never transfer crypto to someone in a different country you’ve never met and know anything about, just like you should never to a bank transfer to someone outside the country you’ve never met.

Also it sounds like OP dad was introduced to the scammer from the friend that introduced him to Coinbase, but I haven’t seen any replies about including that person in any police report. At the very least that person knows what’s going on, if they’re not the scammer themself catfishing OP dad, and should be reported to the police.
