Cryptocurrencies are "created" but ...
We talk like cryptocurrencies are created and "money" is only generated. Back in the 50's my parents bought a house from a family who had lost the original owner in WWII and as a kid I helped my parents clean out the chicken sheds - I found a bag of half-crowns and was so happy until a week later when I found a mold that I showed my dad and he compared it to the pile of half-crowns and then handed the entire lot over to the local police. I started reading at the local library and saw that coin manufacture has been "traditional" for centuries.
So cryptocurrencies are just computers following tradition.
