I began investing in 2005 while still in medical school. In 2007, I started trading on the Brazilian stock exchange. 

By 2008, I was investing in the forex market using automated robots. For many years, I saw good returns with my stock portfolio in Brazil. 

Through day and swing trading with robots in forex, I had excellent years and others not so much; my results were unstable, though I tended to win more than lose. 

In 2020, I started investing in cryptocurrencies with robots, and in 6 months, I turned $32,000 into over $1 million. I stopped trading and exited this market upon identifying the end of that bull market cycle. 

Also in 2020, I began to study macroeconomics in depth, which became part of my analysis process, using fundamentals in my analysis as well and keeping up with new technologies. This is how I identified opportunities in cryptocurrencies, recognizing a time when the macroeconomic scenario was favorable, blockchain was an emerging technology, and then I developed a portfolio strategy that had an edge in selecting cryptocurrencies. 

Nowadays, my strategy is focused on long/short in the US stock market, aiming to buy (long) the best stocks (usually large tech stocks with high growth potential, solid business moat, but also some excellent defensive stocks) or ETFs of the best sectors and sell (short) ETFs that have poor strategies and/or prospects.

Marcello Vieira - Investidor de Sucesso

I founded 'Successful Investor' while working full time as a doctor back in 2012, teaching people how to invest more effectively.

The strategies have evolved over time, but I only teach what I do with my own money.

We now have over 15,000 students learning about investments in crypto and stocks with the goal of achieving financial freedom.
