How do Bitcoin traders know when it's the best moment to sell and then buy again?
How to get that moment just before the crash?
How do experienced traders keep holding and predict the best sell time just before the crash?
It is simple, they buy Altcoins on its DUMP state, then sell it on its PUMP state, just like that, for them to easily know when is the right time to sell their Altcoins and they are going to wait when someone's is going to DUMP his Altcoins and they are going to buy it, and sell it again in the right time. This process is just keep on repeating all the time, that is what the Traders do, though we have our own ways on Trading, this one is the most used strategy that I am seeing that is why I suggest it because it is really effective for us not to lose any profit.
But if you buy them in its dump state then there is a big risk of loosing them as there is no guarantee that its price will pump in coming days and it might disappear suddenly and that will be a big loss for you so instead of taking that risk its better to invest in high potential altcoins with a good volume so even if you need to wait for a long time to make profits from it you will be secure that you will not making at least loss from it and it can give you good profits in long run.
