I did some research regarding Smart Contracts and I can say I did not conclude to anything specific.
Do you really believe that Smart Contracts can replace a lawyer?
And has anyone actually tried to have any kind of exchange and used one Smart contract?
Thanks, everyone in advance who will answer! I would love to hear some opinions.

Smart contract is not that smart i think. But smart contract can make many things easier than before.
For example if everything can be handled automatically, of course it will make us doing too much efforts.
I have not try smart contract in exchange, what i know is smart contract for sending coins or tokens.
