It has not only spread its influence in the Middle East countries, if you see that the circulation of Bitcoin has increased in almost all countries and crypto currency is very popular in all countries. If you pay attention, you will see how many countries like Bangladesh, Pakistan, and Sri Lanka did not use Bitcoin or Sat currency before, but now many people use it, but it has not yet been legalized. But it is understood that Bangladesh government will never give legalization because the government has no knowledge about this crypto currency or digital currency but if you see India and Pakistan it is well practiced. If the government understands or if the government understands its exact demand, it will invest on the government and it will increase the circulation in Bangladesh, but the demand has increased fairly well in all countries. By Middle East you mean only United Arab Emirates, in which case the United Arab Emirates has a lot of expansion and a lot of stock markets on it. There are many things to do in the UAE due to the constant currency.
Most South Asian countries are not very friendly with Bitcoin and cryptocurrencies, the most probable reason for this is that they don't feel safe with it as they know it is something they can't control, and we know what governments do with things they can't control, they either ban them or try to make them disappear. Indeed, most countries you mentioned didn't specifically ban cryptocurrencies, but they have policies that are against them, especially in the financial sector.
If you are living in one of these countries, and if you are involved in cryptocurrency trading or anything that involves cryptocurrencies, you will need to be vigilant if you are using a bank account to send and receive transactions that directly or indirectly involve cryptocurrencies because you can get in trouble for doing that.
