Most probably India will launch its altcoin.. And so will other countries
If each countries try doing this what it means that btc demand will fall drastically as countries will be banning other coin and only their coin will be valid. This also mean their coin could be only used in their country as no other country will allow other country coin then.
Exactly, very well said, for that reason it is best to be vigilant and be cautious so that investments can be managed in time according to the change in the situation.
If countries start having their own govt coins, naturally there are chances that they may ban others.
