Well not all of them is scammers if you choose a mentor please choose your neighbors your relatives or friends that you can easily called if there is a problem with regards to your trading woks, don't engaged with people online or to strangers they will surely block you in all social media sites if they get what they want from you, in crypto i think we need to be more wise on choosing people that we can trust because money is everything and anyone can do bad things because of money specially when they are in a badly need of it.
I would rather not let the people around me know I'm into cryptocurrencies because even your close friends aren't trustworthy these days. As you said, money is everything for everyone these days, and you never know who might deceive you for money. Also, what's the point? If you think you are smart enough to get into a market with so much uncertainty and unpredictability and still be fine, then you should be smart enough to learn everything on your own.
If I think I can't manage my trades or the trading career that I'm about to start, I shouldn't get into it at all. Things that involve finances, especially if it's done on an individual level, should be done by a person themselves so that whether there is profit or loss, it's only that person who knows, there is no shame, nothing to worry about, just keep doing it if you think it's working, or stop if you think it's not for you.
