São Paulo is nice, Satsconf is great. I recommend you also consider btc++ in Florianópolis next year, one of the best cities in Brazil to chill out in the beaches. 

 Loved floripa!! Definitely gonna have to make it out one year and bring my Brazilian father in law. Such a beautiful island 

 How’s the Bitcoin adoption on the island now? I went back in 2019 before I was a bitcoiner
