Keep in mind that EOS goes live 6/1, and there's a rumor that it will have a competing decentralized social network to compete with Steemit's. It could explain the dropping prices of STEEM and SBD lately too. I'm not sure what is going to happen in the future, but for now I'm still buying when prices get low. If EOS ends up with a better solution, I'll gladly switch. I just don't think it is going to happen that quickly if at all.
