Just by concepts alone, steemit has an edge compared to other cryptos. Bitcoin itself hasn't been adopted to a level that you could use it in replacement of fiat currencies.
Steemit on the other hand has already built a platform on which everyday people can use the tech promised. Other cryptos are only selling concepts and vague promises that may or may actually happen.
Well put!
Another thing I really like about Steem, is the fact that you lock some steem power as savings. This gives the equilibrium needed for the system , meaning that your savings can go up if Steem goes up. For the believers is a win win. Supporting and profiting at the same time. It was so well thought, I can´t see it not going up in the long term (years)
