Well most folks do mistakes bitcoin as cryptocurrency as a whole ( which is not right though) , because cryptocurrency is like the general terms use for all digital currency, and bitcoin under that category of been a digital currency. So bitcoin is coin on is own , and it's the first of its kind (digital currency), that's why is the king of all digital currency, like the original . (Now am making it sound like a movie

) ,
The best way to learn is excepting your mistakes and taken correction, so nice one 😁 GIF-JOBS, this shows that you are here to learn and to expand your bitcoin knowledge.
He who fails to learn things the right way we surely learn it the hard way. They will get burned by altcoin, or they will realize too late that Bitcoins value and principle are unparalled. Either way there is always a lesson waiting for them. Based on the way they classify Bitcoin as cryptocurrency they will see need to start investing in other coins that might make them regret in the future and if they lack belief in Bitcoin then its more likely they will still procrastinate and not start their investment journey.
Bitcoin isnt jsut the first but the foundation of the decentralized space. No other currency replicates this trifecta. Yet people still classify it under cryptocurrencies where the name has been condemned with the performance of shitcoins.
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.
