Here is the number(s) that help me sleep tight at night; 40-60k active accounts defined as logged into in the last 30 days on Steem. We are talking about overtaking Google and Facebook. 1 million active accounts should theoretically pump the Steem price to 20x today's price. Facebook has 2.1 billion active accounts. There isn't going to be one decentralized social media website, there is space for many with hundreds of millions of active accounts.
