Some even sell properties and other stuff they own only so that they can invest the money in Bitcoin. I believe that shouldn't be done unless they can afford to do that and won't have any financial problems in case the price goes down after they make their investments.
In this case, of course, the assumption you convey is correct, for those who already know the pattern and continue to update the BTC price history per time, I think they will be more relaxed seeing the decline a few days ago and will not hesitate at all to continue collecting BTC by installments or DCA. There is a good point that I take from you, of course it is very relevant if someone will feel very comfortable investing if everything is in accordance with expectations, both regular monthly income. But other times and opportunities are predominantly not the same for each person's condition. This is the real obstacle.
