In trading, you have to accept that you have to change your strategy because you cannot keep up with the changing market system by applying the same strategy.
You need to clarify this, for I don't see it appropriate, or should I say I see it misleading. I would agree with you if you are referring to having more than one strategy, and then using them interchangeably when one strategy can't read the current market situation. However, if it is about changing your strategy all the time simply because the market doesn't behave the same way, then you are doing yourself no good, as that is called "style drift" in trading. It is not good.
What strategy does someone need besides to buy low and sell high?
This mindset put me in trouble last year, it is a newbie thinking. I wish it is as easy as said it. With your simple mode, it simplest way to trade, it cannot know when the time is ripe for the low to buy and the high to sell. You will guess them. This is not a strategy, but a pattern.
My opinion is that if you are not someone who can affect Bitcoin's price via directly or objectively, then I can't imagine what strategy will help you to profit.
No one can control bitcoin.
