How many people actually know how to write smart contracts
Almost less than 1% of the investors who are supporting or holding smart contract based tokens like lisk, eth, neo. They have different coding language so the one who can develop smart contract in one platform can't make one in another platform.
Lisk uses javascript while ETH uses its own coding language.
Smart contract is just being used to develop tokens rather than any useful products or to be used in real life.
