Dips occur by chance and it's not something you just fold your hands and wait for before improving your game in Bitcoin accumulation, remember Bitcoin price is volatile and if you buy continuously you'll be able to buy at both highs and lows and increasing your aggressiveness if you're able is increasing your purchasing power to get more quantities per purchase which would amount to something tangible on the long-run.
IMO it's not a good practice to be whimpy in your DCA because you're accumulating funds for your target dip and what if the dip ends up not happening, then you'll have wasted time and chances waiting for the dip while you could've spread some of the funds across your buying period and if Bitcoin price continues going higher, you'll regret not being as aggressive as you could be simply because you were being unnecessarily conservative and waiting for a dip that didn't end up happening.
It's about proper planning and you've got to maximize every chance you've got to acquire more quantities of Bitcoin for yourself.
Sure, Bitcoin is a very unpredictable asset, and we don’t know what tomorrow holds. The price changes have disappointed some people since they believe Bitcoin is an investment that will continue to rise without dips. That is why using the DCA plan is so important for each investor. With DCA, you can buy whenever the price is high or low, and this allows you to build up your holdings over time without worrying about and asking the market.
However, if you continue to buy according to plan, you will not panic if the price goes up or falls since you are accumulating gradually. The advantage is that you will end up with more Bitcoin in the long term, regardless of any changes in price. As you said, instead of waiting for a perfect time that may never come, with DCA you will grab every opportunity to continue building. your portfolio.
I disagree BTC has been a mortal lock to go up if you hold it 10 years or longer.
that is the exact opposite of unpredictable.
