I ve seen many threads asking whether we are entering into a bull run or market will crash again. To me, the bull run is already here but it takes only experience to identify it. One key characteristic of the bull run is that, every drop is an opportunity to buy. During this period, the probability of earning profit from your investment (whenever there is a drop) is far higher than the probability to lose. Don't sit down and wait till Bitcoin hits 20k again before you realize we are in the bull run. Try and make enough profits now that the market is booming before its too late.
The problem is the greed of people. Many of us bought Bitcoin for 4 thousand dollars and we can already fix our profit in x2, however, people are greedy and want to see growth to 20 thousand dollars and earn x5. As a result, they can only wait for the price to return to 4 thousand dollars.
I believe that you need to constantly trade and play on price fluctuations. The main thing is not to be greedy.
