This made me want to do some digging. So I made this: https://steemit.com/steemit/@trevorlyman/steem-growth-outpaces-bitcoin-during-past-60-days

You're right, Steem is growing much faster than BTC so it's reasonable to believe if BTC hits 100K STEEM might hit $1k, given 10 more years of advancement, etc.

But I think we're going to see an explosion in Steem with some of the new improvements they have lined up.
