I trust your opinion though only few Knew how to use DCA up to now ,
but indeed that you are calling all to use this method and strategy to have ready positioning once the market go sideways.
what is important now is that we have big part in top ranking coins.
DCA is not that hard and even with that there are a lot of people who do not understand how to use it properly. I get that it is not going to be something that matters that quickly, so it should not be an issue but that doesn't mean that we are going to end up with an issue for the long term. If you can just simply accumulate bitcoin and some good decent alts as well, then you are going to be making a profit during that period.
This is such a simple idea and yet there are a lot of people who fail to do it for some reason. I personally never had any trouble with DCA nor had any trouble making any profit thanks to that as well. It should be a normal thing for many people to keep doing this way of profiting from crypto.
