I accept PayPal and Crypto payments but so far all of my customers have chosen PayPal over crypto.
you don't have to worry, most of your customers would have been used to PayPal payment, all you need is to make the two options available, both PayPal and crypto means of payment, with time you will begin to attract cryptocurrency customers as well who will prefer it for their payment.
Every time that I've offered Bitcoin as the only payment method available I've ended up losing the customer.
you don't need to make cryptocurrency the only payment means for now just in other to keep your business running and for your old customers to keep with patronage, it will come to a stage they will begin to make request for other means of payment such as crypto, but before then you need to keep your business running, had it been you have not started with accepting PayPal that is another different case, but now you can't just come up with a change and expect it to be fully implemented, in other for you to still maintain the interest of your customers on your business, don't mandate cryptocurrency payments but rather make it optional.
