Are you playing to lose or you are playing to win? a friend of mine lose all his bitcoin to trading and when he started complaining about i decide to take a look and i detected that he traded in a gambler's way.
He has 100$ and he traded just twice with 50$ which results in quick lose,im not an trading expert but most trading platforms always warn traders to limit their trading to the highest of 10$ which would have given him more chances to continue trading
Apart from not learning how trading works he is playing to lose,i think this is what many newbies are doing as well,if you are doing the same you will always end up losing your money,if you want to bet 50$ on a trade you must have thousands of dollars on the trading platform not trading with 100$ and be praying for a miracle.
Trading is not something you can rush,expert traders out there spend days trading for profits and if a particular day is full of loss they quit trading for that day.
There are different type of new traders, some newbie trade even without an idea and knowledge because He/She is thinking to earn quick in short they are depending their luck fortune, Then some newbies doing trade because they knew the consequences of of trading, therefore they knew that winning and losing are the only can be happen to them. So your, friend probably became optimistic by it, because of his behavior. Though, I agreed with you that trading is not something you can rush, that's true!
