Market is unpredictable and there's no way that you could really able to predict on what's ahead because it is really that on random when it comes to that kind of behavior on which this had been the typical thing that's why using up indicators or any tools is something that relevant or it's a must because making out decisions on random manner or guess is just really some pure gambling which we know that it isn't something sustainable for longer runs.
That random and unexpected stuff (like luna crashing for example) is the main reason why crypto is so profitable to be fair. Because, regular stocks and other stuff will not be that much unexpected and we all know what is going to happen with them and even though the market crashes, that impacts crypto as well so it is not that much of a difference.
However, because bitcoin is so volatile and there are unexpected stuff, we never know when we should invest, and the moment when it does nothing unexpected and just goes up, everyone profits from it. This is why not many invest, and only few make that profit when the timing is perfectly set. You should always be ready for that up, because it will come one day or another.
