There are deductions to capital gains tax, but they do not apply here as cryptocurrencies are not considered property but instead an agreement between the users, if I understood correctly. But regular currency trading losses are not deductible either (per KHO:2015:178), so I guess crypto is not really unfairly discriminated against in this case.
