I joined Steemit just a month ago and this platform is now my hobby. Besides thinking of it as one of the leading future crypto currency; which it will be surely, It is also a source of great knowledge and a platform to create a change. one can do it by himself as well. ( By posting his own good content).
So I definitely second you that steem will be one of the leading currency in near future :)
How near is that near is yet to be seen but Steem cannot be ignored for too long. I think it is a matter of months before Steem rocks the blockchain world.
