Then I answered that Bitcoin is an platform that one can make payments of purchase of an exchange or a means to receive payments of diverses of transactions such as payment after work done like we are as your employees.
Before you invest in Bitcoin you have to understand it from the basic knowledge so that when someone asks you can be able to explain what is Bitcoin for the person's interest. But from what read in your story or explanation of Bitcoin is wrong so I advise you to go and correct that mistake in the thread and also tell the person again that you did a mistake while explaining the meaning of Bitcoin.
The way you spend your fiat currency is the same way Bitcoin is also spend but it is in internet because there is no hardcopy of Bitcoin but all softcopy which can be transmit from one person to another. I know that it is a mistake and you can correct it. Most of us have made it so it is not a big deal to correct. And from the naira sign you used, I believed that you are a Nigerian.
