I don't know how you can attract new investment but you certainly won't attract it by running away a lot of people. I have been on Steemit for nearly three years, it has never quite worked out to how it was at first promoted a place where you can actually make money for your content and this basically is because of the finite reward pool just think if it were 1 million posting every day. Knowing this, the problem was and still is that the big players manipulate things to their benefit, with hard forks, with bid bots, with curation circles etc. Now, don't get me wrong I have no problem with a person who put in a lot of money expecting to get it back plus a profit that is only fair, so yes, go ahead with hard fork 21 but don't try to portray it as a means for Steemit to be saved because it isn't, it is a way for the bigger investors to at least get some of their money back.
