The altcoins are now getting independent, they are moving away from the shed of BTC. The real value of a currency is backed by it's usage, and BTC has failed in fulfilling what it had promised, Decentralization and power to all. Steem is also centralised in some ways but there are alternatives being developed like SMTs.
I guess sreem will reach $10 by the end of 2018.
To my mind 10$ is way to high and may occure in another „crash“.
I guess it will be at around 5$ during July/August and maybe a stable 7$ by the end of 2018
