I don't know what's the matter with poloniex, They block steem withdrawal every now and then. Steem is big and steemit will be bigger. Steem as a currency may turned out to be only a dream. With other tokes e.g. EOS, ethereum and of course Bitcoin, it is pretty difficult.
I even fear for the steemit, though it's becoming popular day by day and it'sprize pool is decreasing greatly, I do think that, in the future it'll face huge competition from other established competitors like facebook and reddit. And who knows if other social media platform starts to pay their users for per posting. People will leave steemit in a single second. What if steemit closes it paying program. What then? If it happens, people will left it and directly the steem prices would fall on the ground.
So, it's the matter of time. Who knows what happens next. Fingers crossed .
RE: The ultimate dream for me would be a Steem blockchain that is so big and widely known that Steem tokens would be an acceptable form of currency (all the time).
