They may have a small contribution for now but u cant deny that ,with such a huge mass they have a great potential to b a big contributer in future.
and if they are banned from using it ,it will certainly send a bad message in other countries for sure
that potential is now gone. there won't be any contributions. there's no point imagining what might have been.
anyone surprised by this is crazy. india prohibits gold importation and was happy to destroy the wealth of a huge percentage of their population to force them out of cash. i'm surprised it took them this long.
if i were any type of crypto investor i would never have gone anywhere near india because a move like this was so obviously going to happen.
