Nigerians are very strong people in any situation we found ourselves we must survive, as for the mempool congestion it was meant to happen, when their are more unconfirmed transaction and more coming what do we expect, I think to solve this stuff is to improve on better transaction accelerators because if this eventually continues, it might lead to where new investors will be thinking otherwise, bitcoin is improving daily, ordinarily it's transaction processes are expected to improve too, this will enable it's smooth usage, how will be using an amount that you are suppose to hold or exchange to pay for a fee for fast processing of your transaction no matter how it sounds it is very annoying most times, every one is not meant to hold at the same time, though this is may thought.
