How high the bank fees in your country?
I don't think it could be higher than Bitcoin fees if we're talking about daily usage.
Right now the average Bitcoin fees around $2.5 per transaction, I consider it's really high especially if you live in a country where $2.5 is worth of 4 meals.
But, let's see how it goes, you're also show the Bitcoin address here which make anyone can check it anytime.
I'm also thinking about it. Maybe the fees for the bank payment in his country is very high, that's why they are seeking for the alternatives.
The problem is that in my country, bank fees for payments if you have different banks then you will only be charged around $0.5. Meanwhile, if it is a fellow bank, it will be free. And even now there are many gateways to bridge users between banks so that the costs are very small and it is very successful and easy to do, and the transaction also runs quickly. Meanwhile for the use of Bitcoin, it seems it is still above that. That's why at the moment, in some cases, the use of Bitcoin is still low in interest because it is related to fees and transaction times.
However, in my country it is actually not possible to make payments with Bitcoin or other cryptocurrencies, it is considered illegal and restricted. So, yes, it will indeed be difficult to implement payments with crypto, unless it is done secretly and there is a special agreement.
