i've seen people playing games and they get rewards from steemit just by streaming games through DLIVE or DTUBE, but that's a good idea that steemit should have a games too that is base on DAPP or steem blockchain. but when it comes to a promising future of STEEEM and STEEMIT what i could say is i'm still continue posting until 2040, i could not imagine how SMT will transform businesses and i believe it's a game changer if SMT is ready to use by the people.
