I kinda of agree with you. But please do know that till date there's no true peer-to-peer currency. You need the middlemens to process your transactions be it in the shape of Exchanges/Banks/Miners/Block Producers. If either of them stops working for you, your blockchain may turn useless.
Crypto and Banks can definitely co-exist and that will be the likely scenario in the near future.
I agree, but do you think banks are going to do so, and certainly as there is a demand of peer to peer currency where no middle agency is involved and that is what Nakamoto has suggested in his theory for proposing Bitcoin. In current period it would look impossible to have such system, but believe me its all about acceptance in people which is already happening.
Only time can tell. Whatever that contradicts with the governments is destined to fail for the time being,.
Exactly. Its all about intentions.
