Just to understand, I do not see the possibility of short selling on exchanges...
It is possible but it will be with a loss all the time.
That is not a move of someone who has the experience and knowledge in trading. People or traders that always let emotions play a role in what they do as well as those with weak hands will end up with losses. A coin dump is not something to which we react with panic, it is something that we consider a good time, to buy, an opportunity. traders should monitor the chart for 24 hours to make a profit, because the actual fluctuations are still moving at a small rise rate and that's where the real profit is, unlike the shitcoin because its value will not disappear, the red color is the most appropriate Time to buy, don't get used to buying at the price correction as the market continues to move quickly.
When you want to earn profit, that is the time you must to focus on chart price.
Then, take advantage all your experience and knowledge into trade, you will earn many profits
