Lol..this got me laughing, I guess you are the one that freaked him out, which is why he made his stand never to invest in cryptocurrency. You should have also encourage him by telling him how to pervent himself from getting hacked by putting his coins in a cold secured ledger or cold storaging. There might be a lot of hacking going on but bitcoin investment is worth more.
Ya, you are right, bitcoin really worth it even admit all hacking. But the guy is neck bend on not investing in any cryptocurrency. I even tried to tell him how to protect his coins but he won't even let me. Well, I let him be. Probably, in the nearest future he will understand what I have been trying to make him understand.
