"Marketer and crypto bro"

I've been working with Vadim at the same company for over six years. He initially hired me as his marketing assistant, and over time he introduced me to cryptocurrencies and blockchain technology. Everything I know about them is thanks to Vadim. I adore him for his subtle sense of humor, which is on the edge of sarcasm and ethics, and I'm grateful for his experience, which helped me avoid critical mistakes.
