it can even increase while waiting and the investor would regret not buying while it's cheaper, that's why so many investor think the DCA is the best way of owning more Bitcoin cause an investor don't need to wait for the current price to drop below 90k, they can start with that method at any point and still be on the profit side if they invest for a longer period.
I feel people who wait for the price to drop before buying Bitcoin are those hoping to take profits when it increases again for example, someone hoping for Bitcoin to drop from it's current price to 70k so they'll take profits when it increases again and probably get above 100k but they'll eventually fail cause Bitcoin is currently bullish and would keep going higher so it would be wise to implement the DCA method instead of waiting.
If it is still in the accumulation stage, it seems that routine purchases are better because we need to increase our consistency in accumulating bitcoins. Balance in making purchases can be applied once a week if it is done with the DCA strategy.
Waiting is the second pattern by utilizing reserve funds from the cash flow adjustments that we make in executing Bitcoin.
However, do not equate our strategy pattern with other people's patterns because it will be very contrary to our initial plan. For example, if we target investment for the next 10 years, of course what we have to do is buy regularly every year to achieve the target we want.
Investors must be sure of the method they have prepared, they must be able to overcome many temptations at times like this, for example, do not be tempted by short-term profits because the goal is long-term.
