If yotu don't really have heart trust me you cannot gain much from cryptocurrency. Risk is what keeps us going, inability to take risk might cause financial disability. Sometimes you realize the market is not favorable yet still you have to throw in some investment to see the outcome. Lets not forget what they use to say "the greater the risk the greater the outcome".I normally do long term investment but when things are getting worse i just switch my style to short term. That is what keeps us moving.
Why you cannot make big gain from crypto currency market ? I have seen many people already had made some big fortune out of crypto currency market but by carefully choosing the right coin at right times. You must need some good experience in order to find gain from crypto currency market. Your experience will help you to manage your risk effectively.
