How will Google receive crypto payments?

As a keen observer of the intersection of finance and technology, I'm intrigued by the potential for Google to accept crypto payments. Could you elaborate on how Google might implement such a system? Would it involve integrating with existing crypto wallets or creating its own wallet solution? Will it support multiple cryptocurrencies or just a select few? How would the transaction fees and settlement times compare to traditional payment methods? And finally, how might Google ensure the security and stability of such a payment system, given the volatile nature of cryptocurrencies? I'm eager to understand the practicalities and implications of this potential shift in payment landscapes.
