Don't go by the numbers. Less than 5% of Indian population have ever heard about cryptocurrency and those living in the smaller cities and rural areas are completely unaware of it. There are less than 10 million users in local cryptocurrency exchanges. If you add the P2P users as well, then the figure may come to 20-25 million. But still there is a good chance that there are more users in Nigeria (at least in terms of number of active users).
Where are you getting your numbers from?
Less than 5%? You make it look like India is a real shithole where people are so ignorant about tech leaps and cryptocurrencies unlike Nigeria but you will be shocked.
Let's not forget that Nigeria banks, CBN , banned financial institutions from helping in crypto transaction and it's not a huge surprise to me because in Nigeria 70%of the population get their daily bread from crypto and they have to adopt the p2p method
Last time I heard there were bans in India too. If I am not mistaken the bans were first heard of in India, so I wouldn't be surprised that we have so many of our brother and sisters from India using p2p too in a bid to bypass the bans.
