It does not matter at what point we enter the market and start to DCA. Bitcoin has been expensive to start investing at all prices to procrastinators. It was expensive at $1, $10, $100, $30k, and $60 and it is close to $100k and it could be worth more than that shortly. Yet they still can't afford it.
People who still think Bitcoin is expensive usually also tend to be afraid to buy at any price, so people like that will continue to delay and postpone buying Bitcoin because they always put forward their own reasons when asked by other people. Because for those who like to buy or really have the desire to buy Bitcoin whenever they have money that is not used, that person will not really care about the price as long as it can make him happy after buying Bitcoin. I also still like to use DCA when I want to buy Bitcoin, but sometimes I don't set a time for how many times I can buy Bitcoin each month because I sometimes like to buy when I have money that I don't use for other things.
If they look at the price as a whole then they might really think that bitcoin price is expensive. But if they would look at the volume they possibly can accumulate depends on the amount they are willing to use then with that they could able to think that bitcoin is reachable and they can accumulate at anytime they want. But usually those people think about that is a complete newbie and its understandable on why they think about that. Then much better to correct all their misconceptions and guide them on proper information since for sure that once they learn about DCA and how properly used it then provably that there would be no expensive price they would ever thin and people will continue to accumulate to increase their portfolio then earn competitive figures in future by doing long term hodl on Bitcoin.
DCA is a strategy is really the most ideal strategy to use since all people could do it without getting any much bigger issues..
