thank you for your opinion. the fact is, cryptocurrency is not a label, it is the type of currency that bitcoin is. you will not stop this accurate descriptor in the wild. in my experience for successful onboarding it is better to differentiate between cryptocurrencies by, as you said, just saying bitcoin...to which i would add, all the other cryptocurrencies are called altcoins (aka shitcoins) to btc maxies...and here's why etc.
imo, if the video said that bitcoin is a cryptocurrency but not like others we btc maxies call altcoins or shitcoins, because bitcoin is bitcoin and there's a reason why it's #1, and here's why, then the point would be clear
