The overall sentiment is kinda a no-go, but still something wont let me remove the thoughts that its a natural step to take. Same as traditional banks have taken over our RL funds. It might be too early for it, buuut thats why i'm thinking about it, if you know what i mean 
Do you remember the time when nokia Mobile Phone Company had a more than 60% share in the market and was considered as the leading/father of the mobile phone industry ?The arrival of Apple outshined nokia and later on when Samsung started its journey, NOKIA was completely wiped out of the market unless Microsoft purchased the company and reintroduced it. So same will happen in the banking system and crypto banking will rule the world in future.
