Losing huge amount of income will really give u a hard time but that is also the way to gain experience. Next time try to analyze the situation before jumping into conclusions, Try also to read about the potential of the coin before investing.
I think it is called as experience, if you have some good times, thanks to God for making it for you, learn from it. If you have bad times, dont get panic, be patient and tell yourself to control. Right dont have fear of losing, it is the part of game and you have to face it.
