I've seen it happen a million times. It's always the same, none of them did any due diligence, they got into Bitcoin because they heard it on mainstream news and have no long term notion of time. Those guys should have never been involved to begin with, they most likely have legitimate gambling problems
What kind of due diligence do you refer to?
And more importantly, whatever it might be, I'm not sure if it could tell you that the price first would rise to almost 20k and then crash to nearly 3k. Bitcoin is a speculative asset, its price is determined by a host of random factors independent of each other and which have nothing to do with what due diligence typically deals with. If anything, due "due diligence" would tell you that you should stay away from Bitcoin altogether as its price is totally unpredictable and can truly be any, like 10k today and 1k tomorrow. That's my opinion
Once again we hear a sad story of gambler, you know here most of the threads come and gone about their losses, but in the end we can't go anything for them. So if you needed to reach out somewhere then you should changed yourself, and also change your gambling style. Truly, I speak, you can't recover your loss so better forget it and once again start your saving in bitcoin
Well, trading is not gambling so OP should stick to either of the two. As a matter of fact, he should have stuck to his guns with trading
Move on and play straight forward, mistakes can't be undone but in the other hands you'll be able to work it out and learned from each mistakes to avoid another mistakes, this hard losses can win back in another form of investment not inside gambling but another forms of investment, you need to work out with good research before dealing again if you are willing to or very keen to recover your losses
If OP doesn't have the mentality (mindset) of a trader (which he obviously hasn't), he may better stay away from cryptocurrencies. This market is not for the weak-hearted
