I agree, in trading we must be able to minimize losses until we can get profit from the trading. There are many strategies that we can use but it is adjusted to our ability in trading. I always provide USD in trading, because to anticipate if suddenly the market experiences a correction and the price of bitcoin and altcoin drops sharply, we can still buy potential coins at a lower price to reduce the losses that arise because we are trapped in high prices.
There is something that is very easy to say, but very difficult to do, and that is to extend profits and cut losses, but why? basically if I make a trade and the market goes against us we have the opportunity or hope that it will recover, but hardly for that, then we have hope with something that in the end will be lost, but what happens if we cut that loss and if we see that it is no longer possible, why not get out? it does not matter if it comes out at a loss, what matters is to cut the losses, and when we are winning then we cut the profits, that always happens, even so that happens to me sometimes, when we learn to do and apply that to perfection we will be much more profitable.
