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.

I believe people can break everything. Smart contracts are highly transparent based on the information stored on the Blockchain, but if disputes occur, everything uses laws to solve and smart contracts like legal evidence for that.
