bitcoin and because of it cryptocurrencies is a growing phenomenon that they can not do anything to prevent it. so if the government wants to keep their control over the market they would have to forget about a total ban of cryptocurrency exchanges and instead think about regulating them in a way that they can keep people on these exchanges and have control over them.
otherwise we have seen total bans leads to migration not prevention. people simply start using other methods of trading, methods that involve decentralization and remove government control altogether.
Perfect. There is big example of this going on right now. When India had total ban of the crypto currencies then its #1 exchanger went down like crazy. The exchanger that is ZebPay struggled a lot over the Indian RBI decisions to make things happen in their own favour. However eventually they have failed badly. Now they have multi billion business and surely cant let it go that way.
For this purpose they are now getting migrated to the Malta and thus gonna serve 20 more countries out there but NOT India.
Its loss of India country now and thus total ban of crypto will always lead to worst cases.
