Steemit is pretty big and the Steem cryptocurrency is fairly widely traded. I bought steem and sold it before I ever learned about the platform and started earning it. You need to really work at it and figure out an angle but Steem is going up in value with all other cryptos. If you put money into your account to power up, it should be returned with interest. If it does fail, it will be a loss but with people invested and more and more people investing every day, I think it's going up.
