If they the Nigerian government choose to close the access to the use of the exchange in the country i think they have every right on that, but it is unlawful for them to detain the representative sent by Binance to negotiate a ground with them on how to settle the challenges of the market situation with the rate at which some of the exchange traders are offering for the market, we can wait for more actions from the governing authorities regarding the detention and if nothing is being done, the international bodies are taking that up in fighting against any unlawful detention.
