I think it has to happen, even $100 Steem would only put us in the top 5, with 1/3 of the market cap of Ethereum. Consider Steem is the number 1 blockchain by activity, and that's with it running at only 0.3% capacity. With the price now it would have to go up 1400x to match the price to blockchain activity ratio relative to Bitcoin.
I think it's taken so long for it to rise simply because it's such a sleeping giant, it takes time for such a large ship to make a turn.
