It must be admitted that blockchain is a good system for restoring slow server systems, I'm sure that with blockchain we can save the transaction system so it can be faster, and cheaper.
My country has banned bitcoin because the government is trying to get blockchain technology in their daily routine and it will take time. Till that time it is not possible to accept bitcoin because of the unawareness about blockchain technology. After they legalize bitcoin people will invest freely in bitcoin and Altcoin and thus the economy of the country will grow up.
Now, a lot of great and famous companies are ready to use the blockchain technologies or started using it already. I believe it will help to raise the economy.
