It's true that buying low and selling high is the best strategy, but few people do it. Where is the bottom? No one can know. The unpredictability of the crypto market is a fact, and the current trend may still fall. Prepare to buy with a small amount of money first, believing that the potential of Bitcoin will be profitable in the future.
Buy low and sell high is the common strategy, all people use this strategy. I disagree that a few people use this strategy, most people actually use this strategy since it is a basic strategy.
Regarding the bottom price, surely it is impossible to predict it accurately. But we can analyze the chart patterns and the price history, this is what we can do to guess the price. Considering the previous bearish season in 2018, I think this time is the bottom of the current bearish season.
