We'll see what? Other factors are more important so I don't think the success or failure of cryptocurrencies will be a good way to prove or disprove what I'm saying.
If it's a worse currency then it would be idiotic for the world to switch to it instead of their local government's paper money or some other asset in order to conduct transactions, save money, invest, etc.
I was saying that specific feature makes it worse than if it didn't have that feature. I wasn't comparing it to any other currency.
That said there's no way in hell the world "switches" to bitcoin or ethereum. That's so much higher of a bar than a healthy market where you can buy most things.
