This belief often extends to a conviction that cryptocurrencieswill eventually supplant traditional currencies and reshape the global financial landscape.
Firstly, you should use the appropriate word which is
bitcoin and not cryptocurrency because you cannot hodli shitcoins and only bitcoin has the potential to grow exponentially and that is why only bitcoin long term invstors are called hodlers. You cannot hodli shitcoins because they are worthless and you will run at loss if you try to hodli shitcoins since they're for short term. JJG, you posted first what I was aboyt saying before me.
Secondly bitcoin will never replace fiat because that was not why it was created and as long as the world exist fiat will always exist since it was created by the government, so don't get it wrong that bitcoin will replace fiat because they will work and in hand. Or have gold replaced fiat?
You are right some forks here keep on using the word cryptocurrency instead of Bitcoin getting most newbies confused they have forgotten that cryptocurrency is just a general word where Bitcoin and other unreliable conis lies.
That is why it is always important to be specific about the exact coin you are referring to so that new investors will also know the coin you are referring to but when the word cryptocurrency is been use it get people more confused.
