Pretty much what I do in most cases when people talk about crypto because you can't really do good in these situations.
If you say you own some, they'll want to know how much and if you tell them it's always something like "so now that you're rich, you can buy us all drinks" or something, or it kills all the fun and they get all sour and start talking about all the loans they have and how hard it's for them financially.. "but you can't know about this since you have a lot of bitcoin, right?"
Sometimes they get interested and want you to help them invest which is also a red light for me because I don't want to be involved, especially when it's alcohol talking through them. Drunk guys would take you to the ATM right now and give you a few k to invest in bitcoin for them, but then they'd get sober and expect it back with % next month.
