1st, I will say it's as result of inappropriate of knowing the secret behind trading before joining trading
2rd, inability to know price of bitcoin ratio and stage before investing
3rd, Being careless to know when due to withdraw without being greed
4rd, ability to notice that greediness can be a barrier of losing the profit you made.
As newbie I'm of a suggestion that it's good to advocate time to learn bitcoin and its chart of market before investing in any part of cryptocurrency investment and bitcoin, as a new investors that want to make profit and don't want to experience losses in investment, we should know the values of coins either altcoins and otherwise before investing
Learning is a continuous process
