1: Use Dollar Cost Averaging (DCA) Technique:
In Bitcoin accumulation, this is very important.
In the DCA way of buying Bitcoin, you can minimize your possible loss because you only purchase Bitcoin when it will drop. Buying a little by little using this method, will surely your investment becomes profitable when there's a new ATH.
All in all, OP has good input, and newbies should know this and educate themselves when it comes to accumulating Bitcoin.
It's a complete process of accumulating Bitcoin.
Not only for bitcoin, but also in all established coins in the crypto market, DCA is still very applicable. But since bitcoin is the most highly volatile one, then using DCA in accumulating bitcoin will surely work so far. I have been DCAing since the start of the bearish market, and it definitely helps me not to be worried with small price drops. And the fact that I’m into bitcoin for long term investment, that motivates me to never be affected with temporary price decline.
