I was wondering if anyone in the altcoin world uses these are are they just for ETH? Is it a good idea to use one? If not why?
Many people in the altcoin world uses smart contracts and they can be found not just on eth, there are some more that runs smart contracts on their blockchain. One good example for this is waves which is my favorite among those who can run smart contracts and antshares. It is a good idea to use one for developers of altcoins since it would be easier to create an altcoin via smart contracts. For users though it is the same as using some altcoins that dont run smart contracts but still they are still worth using for users.
