Maybe you can handle the unpredictability by mastering the movement of a few coins and not just randomly trading. If you are able to master by following up on the movement of a coin, maybe then your chances of profiting will be higher than when you are randomly trading different coins daily. There is a higher risk trading coins that you are unfamiliar with this is why extreme caution is necessary, and you knowing how to enter and quickly exit the trade. When dealing with a very volatile coin, expect volatility both ways, so you have to monitor it and try to be in and out quickly before the market gives an opportunity and takes it back without you profiting like it has happened in your case and situation.
The higher you try the luckier you could get. That is what they believe in, and that is why they keep on trying the do a wild deal and if they are lucky then they will get what they want. However in most cases they do not do what they want and results are almost always a bad one.
Volatility is great for a trader by the way because if you know what you are doing a good job and that should be the worst part if you as a trader fail to use that. I get that not everyone feels that safe, but if you are worried about volatility then maybe trading isn't for you. Like for example I do not use most of my money on trading, over 90% of my money is on long term bitcoin holding, why? Because I dislike volatility, so you may consider that too.
