There is always a possibility for a correction, and that is part of the reason that everyone needs to invest in bitcoin in a way in which he prepares for short-term price moves in either direction, and if he has no bitcoin, then he is not prepared for up.. .so even if the BTC price has already gone up more than 60% in the last 2.5 months, that still does not mean that it might not continue to go up from here.
I think it's not a significant problem. I'm sure with DCA's investment model and the saying we're going to lose money/rugpull will change. Everyone tries to do their best in investing and sometimes the implementation is different. Some say changing habits is difficult, especially changing investment patterns which in the past we often saw people putting in/buying everything at once, everything was considered appropriate and not wrong, but if we lower the tension just a little, in my opinion it would be wiser to arrange it, do it in such a way and that not that difficult.
That's right, as you said, there is always the possibility of a market correction and sometimes it is beyond our understanding and just look today at how it can suddenly go down even though if we look at the graphic data it shows it will go up. So, what is needed in this situation is fresh funds to be able to absorb any downturn. Apart from research and observation before buying, the luck factor is not needed at all here because DCA is a pattern of buying every drop if we have savings.
