I agree @steembusiness.
There is no reason to not have STEEM as one's largest holding. It is the one, that I can see, at this point, which has the most potential. The fact there are real world applications available is really a game changer to me. Being so early in this process means that many tokens are based upon plans. STEEM is actually doing it.
That is the major difference I see in this blockchain and many others out there.
