I had this news something last year or early this year when most of the exchanges that offer p2p trade were seriously getting limited or ban, this was same thing that was applicable to kucoin making them to implement this law but i know that this is a bad move for them, as many Nigerians won't longer patronize them again due to this tax and vat fees.
I think you can use bybit for free without any additional charges apply when making deposits to their exchange.
This is different from the news of when some Nigerian regulators were very hostile against naira/crypto P2P as a result of naira depreciation which is caused by the government poor way of handling the economy but deceiving people that it is caused by P2P. Kucoin is taxing Nigerians a very small amount of money which is 1% of the amount traded on spot trading market which is the tax that you are referring to.
It's ironic they're charging 1% as tax for trading and also 7% tax again for BSC token, though I'm quite curious what view the government has about them since even till now I doubt they have started p2p with naira currency again as ironic as it seems now, while another exchange (Bitget) are charging us a fee 0.5% for selling our coin for naira and I doubt that exchange bother much about our government behavior at the moment. Though will try to find the reason for this 7% fee added now.
