I wouldn't count on this having a huge impact on Steem price.

The kind of money that's gonna move markets is more likely to come from serious institutional-type investors than the small underdogs who hold firm to their convictions in complete anonymity. And if were either-or, Voice is likely to have alot greater professional-grade strengths that'd validate investment in it/EOS than Steem.

I could be wrong.

And either way, it's likely that both will gain in the next bull run...
