Legal to trade does not mean legal to use as currency. Maybe that's the point. As I know India has taxed crypto so far, they are getting benefit but crypto is not legal tender.

In other countries such as Nigeria, crypto also appears to be illegal as currency but some users are brave enough to adopt it as a means of payment. Even if crypto isn't legal then it's hard to expect it to be banned completely by the government because it's definitely a hot ball for them. Governments can control crypto users with their rules, but not with networks like bitcoin. So it must be hard to get a deal on banning crypto globally.
