bitcoin is not a quick rich scheme where they can always get rich in future
Your statement is a contradiction, because a get rich quick scheme is something that gives money in the future. Bitcoin is an investment for the future and that is what every investor is focused on a long term bitcoin investment by buying regularly every week or month through DCA and hodli, so that they can make some profits from their bitcoin investment due to the value of bitcoin increasing and the compounding value of their bitcoin investment.
In my opinion, once an investor's portfolio is fairly decent, then he should be more aggressive and more aggressive in increasing his bitcoin holdings.
It is good to DCA aggressively when you have the funds to do it, but it is bad when you over invest aggressively because you will be short of funds and go back to sell part of your bitcoin when some important needs arises. The level of your aggressiveness depends on the size of your emergency funds. An investor who has 6 months emergency funds can be more aggressive in his DCA than an investor with 3 months of emergency funds.
