OP, one thing that you should know is that, there's no way a Nigerian who is been paid his salary in bitcoin wouldn't use Naira but only bitcoin because that's impossible. You need to convert your bitcoin to fiat in order for you to take care of your monthly needs and expenses. Tax collection isn't that active in Nigeria if you are not a government work or someone tha own a business.
Someone earning 66,666 monthly will pay the tax. Earning 16,666 weekly. That is around $10 weekly with the present exchange rate of a dollar to naira.
Bros... I beg which exchange you dey use wey the exchange rate of USDT to Naira na 1666 make I start to use am. I don dey exchange usdt for 1550 and below over three months.
