Where can I buy quantitative finance with R and cryptocurrencies?
I'm curious, could you please elaborate on your question? It seems like you're asking about two separate things: quantitative finance using the programming language R, and cryptocurrencies. Are you looking for resources or platforms where you can learn about or apply quantitative finance techniques using R, and also where you can buy cryptocurrencies? Or are you asking about a specific service or product that combines these two areas? Clarifying your question would help me provide a more accurate answer.
