yes,its smart contract,etherum will be a very good and competitive altcoin,and maybe can compete bitcoin soon,but today etherum price going down,someone can tell me that tomorow etherum price will rise again?
It will be quite difficult to predict whether tomorrow its price will increase or not, the price volatility is one of the nature of cryptocurrency, i believe thats why trading can also be considered as gambling, because we can't be really sure what will happen next
