I always get the psychology can take all at any time when the coal in this market
Always remain calm in all cases, that's the best problem solving
I think the best strategy is to forget about your coins for some time and dont look the price no matter how much time passes. By this way you can survive in hard times. Current situation of the market is from more than three months and dont know how much time it will take more to grow again, but cool investors will keep their coins for long time.
