Unfortunately, there are so many scammers and thieves who want to appropriate your money that you just have to be very careful.  Including fraudulent gambling sites also appear from time to time.  And I’m not talking about fakes on the Internet at all, there are millions of them, especially now, when a military operation is underway in Europe.  They try to deceive and scare you.  And in a panic state, a person often does complete stupidity.  I think this is the calculation.  For example, a person sells his cryptocurrency for a cheap price at an ultra-low rate. 
We all can only hope that there are still an order of magnitude more honest people than scammers.  And this gives at least some hope for the normal development of civilization.
