Linus Torvalds has said that cryptocurrencies are simply "a great vehicle for scams"
Linus Torvalds, creator of Linux, does not believe in cryptocurrencies, calling them a vehicle for scams and a Ponzi scheme.
Torvalds was once rumored to be Bitcoin creator Satoshi Nakamoto, but he clarified it was a joke and denied owning a Bitcoin fortune.
Torvalds also dismissed the idea of technological singularity as a bedtime story for children, saying continuous exponential growth does not make sense.
I think crypto does have its place in anonymous transfers and stuff like that but the current form of crypto isnt that. First of all it would need to be something stable and crypto is everything but stable.
All currencies fluctuate against each other, but in most cases the currencies all fluctuate downwards in value within very close proximity to each other. You only see cracks start to appear when one currency becomes much weaker than the other ones. Look at the Japanese yen in the most recent days for an example. The big difference is that with the major cryptocurrencies the supply is either capped or very seriously constrained so it actually goes up in value while every other fiat currency in the world goes down in value over time.
