>>60577126 (OP)Generally, talking with girls about anything financial is no bueno. It's usually technical i.e. factual and boring, which is the opposite of emotional and fun i.e. attractive. It can easily turn to a conversation about your wealth, so you'll lose attraction there, unless you're relatively rich or make up for it by being handsome or fun.
If the topic had to be pengu, I'd let her talk about what characters she likes and steer away from discussing crypto/money.
There are exceptions though. In school I was studying with a cute girl from math class and she was very excited to show me her most recent options trades, essentially gambling (which can be emotional and fun).
