Without craving to indulge on a dispute with your contributions which you're all right about, I still want to clear it up by saying for a short term Investors and most especially little investors to stable their emotions while chasing the profits in a short while, the systematic to has sold when we met with the ATH would had been of better DCA reaccumulating approach for such terms of investors because at then, they'd have secured some incomes to buy and accumulate more during the Dip and most diving in by the halving.
While I'd want to see reasons to agree to your theory, I can only say that you're not really investing but gambling with your money because you're acting out of presumption without fully understanding the next action of the trend.
Bitcoin price is very volatile and this makes it more interesting, due to the market's volatility, every other option or approach you decide to employ asides HODLING would be gambling as the market has every tendancy of moving the opposite direction at any time.
Have you considered after taking out your investment because you feel Bitcoin has just hit its ATH with hopes of buying when the market DIPs again, but then Bitcoin experiences even a more Bullish rend and reaches even a more higher ATH and you still sitting there waiting for a DIP.
Now let me tell you what's likely to happen, out of FOMO, you'll be forced or pressured to BUY at the current price in order to join the moving train, but then what if after you've bought at the current price, and Bitcoin price immediately drops after establishing a new ATH, after losing some bucks, you're hoping the market would recover immediately but the more you expect another pump, the more you experience more DIP.
Have you ever considered this possibility? That's what volatility means, you'll end up losing more by trying to predict the market. So why not just HODL, BUY THE DIP (when you can) and DCA and save yourself the whole drama and tension.
