That's the whole point of using smart contracts and blockchain, automated and trasparent transactions and you trust a code instead of a third party
That's true I think in the future everything will be decentralised because people are fed up with third-party organisations. We should not underestimate the power of the blockchain.
The main reason of building bitcoin for Satoshi was to get rid of third-party organisations and prevent happening crashes like 2008. This is the main reason why im interested in projects like ModulTrade. Invest in the future
