The market crash a few days ago may have made many people a little disappointed but if the OP asked this I have a personal reason to explain, bitcoin has a limited supply and why try buying from now on and BTC is not a hidden gem anymore.

However, in this sideways condition, trading is actually very difficult and to get even a small profit we need to hold the position for several days. Now. For BTC, in my opinion, you don't need to spend that much effort, just buy it and hold it for a period of 3-5 years at least, then you will really feel the results.
