There is nothing wrong with following a strategy provided the strategy is adding more Bitcoin to your portfolio. Even Michael Saylor that you referenced is following his strategy why I feel is the Dollar Cost Averaging. He also have his way of buying Bitcoin when there is serious doubts and uncertainty in the market and all the times he came out right about Bitcoin, the reason he is celebrated today as a firm believer in Bitcoin. I also use the DCA strategy which is a great way of buying Bitcoin without pressures.
Yes, it is certainly true that there is no strategy in buying Bitcoin, but I think that strategy is not the beginning. I think that buying Bitcoin when the price of Bitcoin is low is a good time to do it, and holding it for the long term can also be a personal strategy. Yes, you mentioned Michael Sayle, my wise man, who is unmatched by our ideologists. Yes, it is certainly true that there are some methods in Bitcoin, which you need to know before you ask. If you buy Bitcoin following the DCA method, then good for you.
