Hello everyone! Call me Gustavo or ProfessorGeo, I'm a professor graduated from the University of São Paulo (USP). I'm 22 years old and I got interested in cryptocurrencies, the stock exchange and the economy last year (2019). My favorite reading is about the world economy and cryptocurrencies, I also like to write about it, and also technology. I hope guys enjoy my publications and that they are something that arouses in you the interest that aroused in me.
