Ok, so what problem has actually been solved?

Cryptocurrencies accomplish nothing that wasn't already possible before, usually faster, cheaper and safer. Just because someone uses an alternative doesn't mean it's solving a problem, and in this case it's just creating more issues.

I have used Bitcoin to buy various things and used it as a savings instrument, I see that it has solved problems for me. Of course I could use other tools for that, but if you think Linux is superior that doesn't invalidate someones experience who is using Windows.

Generally there seems to be lots of people who don't use cryptocurrencies and think that they don't solve any problems - OK whatever, don't use them, but there are loads of people using cryptocurrencies for whatever and your opinions are not objective measure on their value.
