I agree with your sentiment here, the DCA accumulating strategy works mostly for someone that has the intention of holding for a very long period of time, because since you are buying in different price interval, you wouldn't reap the full dividend of it,, if you aren't a long term holder, so as we are still in the early days of Bitcoin, any buying price now will be very much ok, but in the future, when Bitcoin has already skyrocket to one million dollar, the DCA accumulating approach wouldn't be that idea again, so I urge all Bitcoineer to seize the opportunity now and utilitize the DCA accumulating strategy now that it's still effective.
DCA strategy is just an accumulation strategy that makes it possible for investors to be able to accumulate bitcoin no matter the amount they have or earn and no matter the price of bitcoin. Long term investment is ideally the best but DCA strategy is not only for those who are in for the long term investment and DCAing for a long term doesn’t guarantee successful investment, investing (buying) is a step among the different steps to be taken when investing and to be successful one must also possess certain characteristics like to be able to withstand the pressure of panic selling. long term investors should possess the ability to withstand every downturn the market throws at them and be focused on meeting their targets if they want to be successful.
It doesn’t matter the price of bitcoin DCA strategy will always be useful and effective for people because it is the only way people will get to invest what they can afford to lose and not go beyond their limits.
