In Germany (IIRC) crypto is legally money and that's why you don't have to pay taxes on your trading gains, because it's just currency conversion. (IANAL; consult a lawyer before attempting to legally not pay taxes)

The point isn't whether or not it's money, it's about whether or not it can be property. Money is property.

If crypto isn't property and can't be protected by property rights, then it's quite foolish to spend money to obtain it.
