No matter how you want to analyze it, waiting for the Dip before buying bitcoin is not a good strategy to accumulate bitcoin. Buying through the dips is a good strategic opportunity to accumulate bitcoin but waiting patiently for bitcoin to Dip before buying is absolutely wrong. Yes it is wrong because it is impossible to know exactly when the next Bitcoin Dip will happen and just like you have already stated that"no one can do perfect timing" of the market . Secondly while waiting for the Dip before buying bitcoin will affect your consistency in accumulating bitcoin and may also cause you to miss good viable opportunities in the market that you should have utilize in grow your portfolio. So it is better you stop waiting for the Dip and start buying bitcoin when your discretional fund is available .
Waiting on dips is a strategy for traders not for investors. Investors shouldn't see it as a primary strategy for accumulating Bitcoin, if not they will end up not accumulating any substantial amount at all. When you are investing in Bitcoin waiting for the dip is like waiting for a perfect time to buy Bitcoin but there isn't a perfect time at all. Our primary investment strategy should be either buying through dca or lump sun. And perhaps any other strategy that fosters accumulating and that dont requires you waiting for the price. While buying on dips should be like a top up strategy for times when you have enough more discretionary income to invest with.
