I'm not sure I understand what you mean. Do you consider the middleman banking system a sign of trust? How about the invasion of privacy required by the state in order to collect taxes? It used to be that humans could exchange value without third parties. The third party was introduced exactly because of mistrust, and eventually this practice grew so widespread and big that it became a new industry all on its own. Cryptocurrency cuts out that third party, and makes business a one-to-one interaction again, where contracts can even be fully automated. Of course all third parties out there dislike this, but there might still be a silver lining for them. For the state, all Bitcoin transactions are visible on the blockchain, for instance. This makes Bitcoin inherently less useful to kidnappers and extortionists and so forth... And for the banks it makes the transfer of big amounts of value extremely safe (contrast this to what's going on in South Africa at the moment, where value transports are being violently targeted by cutthroat bandits). It also opens up a wholly new business opportunity for them if they start exchanges and on- and offramps for crypto. Already new organizations are being made that grant interest on loaning out or staking crypto, for instance.
