But we surely will be seeing crypto trading being accepted and taxation on income from crypto which is already present in India.
May be there will be a consensus on how much taxation would be implemented on it and few policies that G20 will bring out together.
All in all things will be baselined for cryptocurrencies which is a good sign since a vast majority of people are still concerned over its legalization.
What I am more excited about is a G20 framework on tax. India has already implemented a heft tax policy but many G20 member countries are not charging such hefty taxes on crypto earnings. By October this year, we should be able to hear some positive news on this topic. EU has been pretty much progressive in allowing crypto as an alternate pay mode in local stores and e-commerce websites. If India allows the same then it would be a convenient mode for making purchases both online & offline for the Indian crypto community.
India won't allow crypto to be used as an alternate source of payment.
Also, the video in your post says that the G20 countries have come to a mutual understanding that crypto shouldn't be used as a form of payment and hence it is not a legal tender.
So I'm not sure how EU will plan on working that out if the G20 consensus derives policies to eliminate crypto as a payment method.
For now we do know that a consensus is formed and policies will be derived for crypto to be used for trading and taxation will be applicable on it.
Since India already has it's taxation policy for crypto it's a matter of time before we come to know that the G20 countries will have the same taxation policy or they will have a flexible policy wherein different countries tax crypto income differently.
