About us

I am Marcelina and I am a tax advisor and attorney. I deal with taxes in the cryptocurrency / blockchain and IT business. I help understand taxes in innovative industries. I believe that everyone should feel safe when dealing with offices and choose the rules of their settlement consciously. I educate and advise on how to run an innovative business in line with the law but at the same time in the most tax efficient way.
I educate through my blog, YT channel, and through webinars and trainings.
I advise during individual consultations and long-term cooperation.I speak in your language – I know the difference between PoS, dPos and POW, you don’t need to explain play2earn principles to me. I understand that you can trade short and long term, and I will not be scared if you use the words on-chain, off-chain or swap while talking with me. I distinguish waterfall from agile methodology.
I do not use legalese in day-to-day cooperation, so you can easily understand what you can do and what you cannot do!
