The good thing now is that you can still earn a nice amount of STEEM through blogging and activity. It's slow but steady growth. In two years time i would guess that it will be impossible to do what we are doing now and earn nice amounts. I joined in 2017 and can only wonder how the first users did so well and grew so fast. I think that will be us to the next generation who will be striving to get to 500SP.
