I think it is not necessary to buy bitcoin everyday specially in times of bull season, because it is so risky to buy btc during bull season, the best time to buy bitcoin is during the dip but not everyday we need to make a proper timing to buy because it involves capital so we need to be careful to avoid loss.
so, in essence one has to wait till the DIP season before buying and even when the supposed DIP has come one will still wait for a very comfortable point before buying? like now that the market is somehow down, you have to still wait for the day that you will get the highest level of correction before buying how will you even know that you have seen the highest level of correction or that the market won't go past a certain point? these are things we can't really predict and that is the reason why those strategy does not work well. well, as much as buying bitcoin everyday does not look realistic based on financial constraint and other issues, over timing the market before buying is another problem on its own.
while waiting for a DIP that can on the maximum save something that is not even up to $5 to 10$ depending on the extent of volatility, it can stop and delay you from getting to your investment goal fast enough.
