As mentioned earlier, experts predict the fall of all crypto-currencies at the end of this year

They may be right or they may be wrong. The market will do what it will do. Many are predicting the funeral of bitcoin but others say otherwise. We can just do what we have to do which is to minimize our losses as much as possible when the trade is not in our favor. If ever what the "experts" said about the fall of cryptocurrencies then it will eventually turn around at the end of the cycle of the bear market. We just have to be patient and wait until such time when we become profitable in our trades again. When the time comes that there is an impending run, the volume would appear then.
