It is not false at all. I don't know where you want to drag this conversation and what you have been told but a currency is the method you use for your purchases and payments. It represents value and is transferable, thus any cryptocurrency is named correctly as such. A currency is also a store of value because it represents a certain amount of value at a selected time. You are probably trying falsely to push the agenda that tells you Bitcoin is not to be used for transaction and with this post try to make a case that other cryptocurrencies aren't exactly currencies either.

Bitcoin is still being used as a currency but in very limited way. In the future with the yearly increasing average fees it probably won't, as if fees reach thousands of dollars, then it won't be used to buy not even a Tesla. But I see that you try in vain to make a case that other cryptocurrencies don't exist and they are named falsely like that. Nobody said that cryptocurerrencies are national currencies. You need to evaluate a lot when talking about this scale.
