I personally think this should be considered as a ground-breaking decision which not only decriminalized crypto-trading but also gave much needed legal status to the crypto-currencies in India.
Do you think other countries should have similar approach to the crypto?
Of course, this is a ground breaking decision coming from the Supreme Court of India, and should consider a big victory for crypto enthusiast around the world.
But as far as other countries? We can't say for certain, maybe this can set a precedence for others to bring the case to their highest court, but I'm not expecting that nations, specially those who have a hard-line stance to simply make a U-turn just because India had a landmark decision, case to case basis.
