Exciting post @flauwy ! At the time of this writing, steem market cap is $ 767 million. Much like facebook, we can only say that if steemit can grow its user base into millions, it will become very valuable. Facebook market value is more than $ 500 billion currently. Suppose steemit reach 10 % of facebook market value, all steem holder will get significant gains. And I believe 10 % is conservative estimation. With all projects development such dtube, dsound,etc, its value worth significantly more than that. Even $ 100 - $ 200 investment could move the needle on your wealth if Steemit become the next facebook.
