Ok, missed that part "capital contribution"
but when SP will be converted in to STEEM in two years, there is can be no steemit anymore and your capital is locked for two years u cant withdraw. is very interesting but very risky when there 99% of coin/blockchain projects are dead in 6-9months. and if not mixing was few very similiar projects to steemit.
but yes, steemit atleast working.
p.s. dont think wrong about me.. i like this project very much and think if cards played right its could be big ... at least not smaller than twitter
