Forget about it and do not think too much about those projects. In my opinion, do not think about the past, forget about what happened to us, so you will succeed.
Almost all the bad luck is actually as result of your mistakes and faults so you have to focus on where you did the mistake. If you learnt not to repeat your mistakes then everything will become fine for you and you will be on the way to get profit. Always buy in low market so that you will not face with any kind of loss later after buying it and it will be only profit when you sell in bull market.
In my own opinion, if you lose a huge amount of your investments then you should just accept losing money because that's how cryptocurrency works, the price will only grow if the market starts to pump up.
