Cryptocurrency will definitely help people become smarter. Using cryptography everyone understands how economics are working, and nothing complicated. So in the future, I think, our kids or maybe even us (who know) will not need a bank. We will see, but the answer to your question is sure
For me, the Crypto-currency teaches us to hope and rely on ourselves, not blaming anyone else. If we lose money, then we ourselves are to blame. Means, we could not record profits on time or did not observe security on the Internet. Crypto-currency teaches us to delve deeply into the essence of projects, in order not to invest in a scam. Right?
