It's not ok for me paying my taxes but it is a liability for us therefore we have an obligation on paying our taxes as well as the other citizens we have living in the same country, to be fair we don't really carry the same burden when it comes to paying our taxes as it scales up depending on which tax bracket you belong and I think it is only fair that the lower income earners have lesser tax liability than the ones earning higher ones.

I think for your case you are experiencing a higher tax liability because you have yielded a higher gain during that year thus placing you on a higher bracket. If you want to reduce your tax liability you should do more research in your country where you are living. For example since I think you are living in a European country there are some countries in their like Germany where you will be exempted for tax if you held your crypto position for more than 1 year. There might be similar laws you have in your country which reduce or completely remove your tax so really there is a lot of options in which you can lessen your obligations.
