I'm not trying to be too hard on you but the only common denominator in every single one of those bad experiences is you, bitcoin is just a tool, it is neither good or bad, whatever happens to you that you do not like while using bitcoin or any other cryptocurrency most of the time is 100% your fault, did you lost your coins to a scammer, or a hacker, or did you invested in a bad project and you lost your money that way? And if that is the case you have my sympathy but you are your own bank now and the only one that is supposed to protect you from all of those things is yourself.
