But time will come I will not regret. That is the risk in the investment of Bitcoin one has to know before entering.
The risk that has happen to you that reduce the volume of your bitcoin at the time it drop into your wallet is same that it will increase when bitcoin will bull so no need to be angry. If you hodl for long you will benefit more than 10% or more.
As it is I don't think Nigerians can buy Bitcoin because of the present situation of Dollar rate and the bear market but any how some are still buying.
No matter the situation in a country people there will survive. Every bad situation is favour to another person. People will not benefit at the same time, some buyers and sellers will still continue because it is their business.
