What are crypto payment solutions?
Could you elaborate on what crypto payment solutions are? In a nutshell, I'm curious to understand how they function and their potential applications. Specifically, I'd like to know how these solutions facilitate payments using cryptocurrencies, whether they're secure, and what advantages they offer compared to traditional payment methods. Additionally, I'm interested in knowing if they're widely adopted and what challenges, if any, they face in gaining more widespread acceptance. Your insights would be greatly appreciated.
