There is nothing wrong with market timing;the concern is that you may miss out on dips that never appear or freeze when the drop does occur.
So what if the market doesn’t dip? You already said it’s not wrong to time the market, w you also understand that Bitcoin is unpredictable. Why would someone wait for the market to fall before investing? In that situation, they are not ready to invest, only trying to find a way to buy at a lower price. Timing the market is a bad idea because you will miss a lot of opportunities to buy. Nobody can tell whether Bitcoin price will reach $70k before next month. If you are buying for the long term, just focus on your accumulation.
Combining strategy can be very advantageous because it will help an investor grow or increase their portfolio so easily, just imagine someone I mean an investor who is using the DCA method and at same time front loading or been aggressive when there is Dip, the investor will grow more than someone that is just using the DCA method but it is not compulsory to combine two strategy in Bitcoin investment especially if it is not convenient for the person otherwise there will be a problem.
Having a combined strategy does not mean your portfolio will grow faster than a guy who has been buying consistently with DCA. Your consistency and how long you have been buying will determine how much your investment can grow. You may have a different strategy, thinking you are outsmarting the market, but someone who invests only with DCA may grow their investment than you if they stay consistent, and even when their budget is higher than yours, even with your combined strategies.
