Planning to start a service/ online store with CC as only way of payment, ignoring fiat completely.

Planning to start a service/ online store with CC as the only way of payment, ignoring fiat completely.

Question- how many different blockchain options as payment is too much?

With options ranging from BTC, LTC, XMR, XLM as obvious choices, should I go with more for the sake of user convenience (passing on obvious scams and rugs) or shall I limit the list to up to 5 different blockchains?

The reasoning behind the multiple choice option is enabling the user to shop with the CC they currently hold as opposed to for example only requesting BTC, not only avoiding the forceful (often expensive) exchange, but also cutting down the transaction fee in some cases.

What would be the most useful to YOU as the service user?

Thank you all for input!
