A colleague of mine was into shitcoins, we started talking about crypto ocassionaly at work, I told him I was bitcoin only and that crypto is a scam, he asked why and I explained the playbook of scam coins, he understood it. Then in other occasions i talked how all fiat is going to zero against bitcoin. Now he's only in bitcoin. So it's a process, education, especially how the shitcoins scams work. Don't try to call them dumb or forced them, but still, not everyone will listen.
