Majority of those people classifying bitcoin alongside cryptocurrency are probably ignorant, if they are enlightened that bitcoin is not crypto currency they will stop classifying it as such. Not many people are opportune or exposed to a learning space like this. So it is left for you and me to correct anyone we come across that's making such a mistake of classifying bitcoin as cryptocurrency. We should make it clear to them that bitcoin is not a crypto currency, but it is just bitcoin and should be referred to as bitcoin. Many of us here today were ignorant of this fact till we came to this forum, especially this thread, that was how we realised that bitcoin is on it's own and not part of any crypto currencies. If we don't enlighten these ignorant people they won't ever know the truth and they will keep living in their ignorance. Not that they ain't open to embrace the the change that bitcoin is not a crypto currency. The truth is that they don't know, so let's help people know the truth whenever we come across them.
