Buy when the market falls deeply, but how much is deep? Buying at the bottom is also risky, as a drop in prices could be a sign that the market is about to crash. It has also adjusted to over 80% in the past. Therefore, you have to determine which price zone is attractive enough to buy. As for where the bottom is, we can't guess. Let's discuss whether to catch the bottom or not and when the bottom is right, at what price will you sell? Do you buy a valuable asset when it falls below the previous price, but is that the final bottom or will the price continue to fall and establish a new low? For asset classes such as stocks, real estate, gold... that have been around for a long time and are popular in the market, bottom fishing is very popular and it has resistances that are hard to break. However, with a new and volatile market like cryptocurrencies, bottom fishing can bring many risks because the market size is not too large, so some sharks can manipulate the market and break resistances. so you have to be very careful when catching the bottom in this market. Should I catch the bottom of altcoins or the bottom of BTC? In my opinion, BTC should only be bottomed because it has been joined by many large organizations, appeared the earliest and is held by many organizations and individuals, so it cannot collapse. As for Altcoins, there are already many coins with a value of 0. Or with coins in the top 20, you can catch the bottom.
After successfully catching the bottom, when will you sell them? That is a very difficult question to answer.
