Purely out of curiosity, rather than suggesting to study bitcoin, I suggested to a normie  exfriend to jump on a bitcoin train, even if just a bit, to grab some profits. I was not surprised to hear, that he is doing well enough (meaning enough salary for mortgage payments and leasing Nissan Quashqai economy interior, 50hp or so), and will not give up his euros for a currency that is not pro ukraine and israel and not contra russia.
So don't worry friends, there is no wrong advice you can give to your normie friends, if you decided to waste your time giving any when not explicitely asked. And even when asked, the best approach is to force only yes/no questions.
