It can be worthless on some areas like the most poor countries in the world like africa. But I think after adoption, there is no stopping bitcoin from having it's value and people will embrace it as the new currency of the internet. I don't believe btc is worthless and only has no value to people who completely still relies on fiat.
Sure are you Bitcoin worthless? with the increase that happens now will make people prefer Bitcoin will continue to be valuable and useful for many people.
I am sure Bitcoin will always be valuable as long as there are those who use it and the internet network is available. yes maybe if you talk like it or not to bitcoin, surely everyone likes the price of bitcoin if it's high, it's just that they don't believe in using it.
