No doubts this are common mistakes alot of traders make usually beginners and it thus affected them, well I think I was caught with with number 3 mistakes of always buying new listed coins just to see how i can be profitable in the long run and yes I would say the coin was over hyped so i didn't want to be left behind so I keep buying but as time goes it's value kept depreciating this putting me in loss. That's a high risk of loss that I took knowing how much I bought those coins but I learnt from it as well.
