on every decline we also have to set a buy area at support, so that it is even more maximal in getting a profit. therefore it is better to divide our capital, do not buy at one price only. because its nature is probability, and of course there will be movements that we don't want, so we have prepared a strategy beforehand
Catching coins at multiple prices at the time of the decline is a strategy that is very often used by active traders in the exchange, because it can always be successful in getting multiple profits through the price variations they find at the time of the decline, so, I think this is clear very good.
