I'm curious about the process of buying cryptocurrencies or assets on Blur. Could you explain the step-by-step process? What kind of user interface does Blur offer? Do I need to create an account first? Are there any verification processes involved? What payment methods are supported? And how do I ensure the safety and security of my transactions on this platform? Additionally, are there any fees or commissions associated with buying on Blur? It would be great to have a clear understanding of the entire process before making any purchases.
