If the behavior of the cryptocurrency led to suicide in February then I'm afraid to even imagine what happened to people this summer. I think there's no connection between suicide and cryptocurrency. I think the problem is the people themselves who can be so upset about anything. In any case, will soon begin to rise and all be happy again.
I suggest get some time for yourself, do not beat up yourself with these market manipulations, get out from your computer watch some movie with your family and comeback when the market has recovered so that you wont have a lot of stressful time in front of your computer.
