Hodl is the way forward if one really want to make profit from investment. One has to exercise patients hodl. That's is why it's good for one not to use all fund to invest or no source of income, so that when it's dip their won't be panic.
Everyone has a strategy in this regard and what you are saying is also not wrong but as long as there are better and good moments to take advantage of, I think investing in times of decline and selling them now is also a move that is not wrong
strategy is very much determined by the level of success of investments that people make, the more experienced people are in investing, the better the strategy will be, there is nothing wrong with investing in conditions of falling prices, this is the right step in making a purchase, but the question is selling , what should we sell on the condition of falling prices?
For example, buying at the current price, then selling it, where can we get a profit, isn't investment a profit-seeking pattern?
