This is true, my mate. I agree with you that bitcoin can be bought at any time and at any price. But here, I will clarify your position a little so that people do not misunderstand. Bitcoin can be bought at any time and at any price, but this does not mean that you should buy bitcoin straight forward on top of your ATH when bitcoin has completed its bull cycle while you are on the way to the bear cycle. Then you bought bitcoin at the top and now take bitcoin, thinking that bitcoin will go over and give me a profit.

So, if someone means that bitcoin can be bought at any time, then I think it is not a wise standard that you buy bitcoin without research, without technical fundamental analysis, and blindly hope that it will now go up and give me a profit. All this does not work in the same way in the field of cryptocurrency, but by doing your own research with a complete plan, you can make yourself aware of all the necessary aspects of investment in Bitcoin, and then you can hope for the profit of investment in Bitcoin. Be otherwise; similarly, blindly investing or trusting blindly can give you nothing but loss.
I hope there is no mistake in my understanding.
