i am okay with some regulations like to control scam icos or fraud exchanges or money laundering .
with KYC this issue can be solved .. so it is okay if they regulate such things ..
but banning it not a solution , after ban govt will not only damage its tax earnings but also a black market may open for this , and people will trade it without coming on radar ...
so better to make it legal with some rules .
I think govt is more worried about its misuse than the tax that would be collected from it and also they would not be able to control full this other cypto currency as its traded worldwide. So what they might do is that if they want to leverage they will ban all coins and only give licences to the top business who wants to bring their coin and which the government can easily monitor or bring some clauses in such cases.
