Basically DCA is just an investment strategy, while this strategy will most likely not have a big impact on your optimism about the future of bitcoin. There are many investors who are optimistic about the future of bitcoin, but they have different strategies, not just DCA. For me, that's not a problem, the most important thing is that they try to make Bitcoin an investment, whatever strategy they use.
DCA is very useful for those of you who want to take advantage of price volatility to carry out accumulation. Even though you can buy all at once at a certain price, DCA can be considered as a backup strategy if the price falls further than the previous purchase. If you don't set aside a budget, then perhaps you are ignoring the opportunity.
Also know that, you can’t force yourself to be in a position of getting opportunity always and not utilizing them. The market will never make you know when it’ll fall in price or a big dip will happen for you to DCA and add to your portfolio. If you’ve already done your lump sum and you can’t afford to set aside another budget to continue DCA anytime an opportunity arise, don’t feel sad or be bothered. The value of your bitcoin at that time will be the same and what you’re looking for is the long term prospects of it, so the dips and fall in price shouldn’t bother you that much after you’ve done your investment using the lump sum strategy. You should also think that, what if the opportunity to buy low never came and the price you brought from was never tested again by the market? So they’re possibilities to this that we can’t control them, you just have to accept the facts of it the way it is.
Any investor that lump sum and the price of bitcoin dips and the investor is worried an out the dip, he should not bother to lump sum again but use the DCA strategy. This is the reason why a new investor should not use lump sum to start his bitcoin journey if he doesn't have plans of regular DCA weekly or monthly buying constantly for a long time, because if he lump sum only ans price dips and remain there for long, the new investor might be discouraged because his bitcoin portfolio has depreciated in value.
DCA is very good to start your bitcoin investment as a new investor because you are buying bitcoin always irrespective of bitcoin price and when there is a dip, you are also taking advantage of the dip to buy more Bitcoin since your DCA is ongoing, instead of getting worried of the dip because he only lump sum. With that the new investor will not get worried because he is determined to keep acquiring more bitcoin overtime and stay focus on his bitcoin target. If he has extra cash, he can lump sum if he wishes to.
