The first and foremost goal of those of us who invest in Bitcoin is to hold our investment for a long period of time. We all have a tendency to buy bitcoins when we see that the price of bitcoins is high then we wait for bitcoins to be low. Maybe many people think this is the best time to buy Bitcoin. But you mentioned that you don't wait for the price of Bitcoin to fall because it can rise again. If you don't care about Bitcoin price going up and down then you should go for DCA.
If you start investing using the dollar cost averaging method, you don't have to worry about the price of bitcoins going down or up. You can buy bitcoins anytime and save them for investment. So set a fixed average price and hold accordingly by buying bitcoins.
It is true that the aim of investing in Bitcoin is to maintain it over a long period of time. This must also be taken into account, because I think not everyone can do this, especially by waiting for it over a long period of time. not everyone can have the patience to wait for a long period of time. I was once advised, when we invest in Bitcoin, don't pay attention to the price going down, go away and don't care about the price going down because he said one day the price will go up again.
Also, I think many people think that the best time to buy Bitcoin is when the price goes down, maybe that makes sense, but for people who really understand Bitcoin, maybe it's not just when the Bitcoin price goes down that they will buy it. Apart from that, there are many things you have to pay attention to if you really want to buy Bitcoin, don't let yourself be impatient with doing it, it's possible that it will only make us experience something bad.
