We can not deny the fact that banks offered more secured system because they are centralized. We can only trust our KYC with them. But when it comes to conveniency, we can trust cryptocurrency. More easy transactions, easier to access and fast to monitor our funds. However, when it comes to secured personal info, since it gives anonymous transactions aside from exchanges where KYC is needed, then it is also give benefits.
There are now alternative ways to manage KYC though like KYC-Chain. They're a compliance solution that offers fast and accurate Identity Documents Verification. It's a step forward for the standard KYC that banks traditionally use which obviously has a lot of bottlenecks in their process.
