i know what all countries thing about bitcoin, they take bitcoin as a risky thing for their economy , it may reduce economic growth , lots of fraud ico and scam sites , anoymity of the users while transacting bitcoins , illegal activities and transaction via bitcoin , there are the major issues according to all countries(except some countries) .
According to my opinion, there must be a new technology implemented , which is, on transaction id there should be shown two identities of receiver and sender , there must be shown receiver's and sender's details(their name their address exactly on the kyc documents)
