I think Steemit is a very unique blogging platform that aims at fairly rewarding users with Cryptocurrencies.
The most exciting aspect is that it is all built on the Steemit blockchain, which enables for much more than blogging. For example, there are social medias being developed on the Steemit blockchain that aim to provide already established services (like Instagram or YouTube), but with the cryptocurrency twist.
Yes. The best thing about the steem blockchain is all the apps that are being built. This will help the price of steem in the long run.
