Worth it or not, the question is very abstract. Because everyone has their own opinion on their own account. But the bottom line is that Bitcoin (or another cryptocurrency) will (possibly replace) conventional currency in the future.
It can be a possibility, it can be not. There are a lot of things that may happen in the future but I think Bitcoin will stay as it is in the future. It will continue as something that we invest in amd we hold in order for us to earn our profit. That just means it will stay as a a investment ir an asset rather than a currency that might or will not replace the conventional currency.
