PayPal vs Credit Card payments

Hello,

I just registered in this forum because I thought I could get my answer here.
I'm reviewing, trying and choosing a platform to make a subscription for my supporters, like Patreon does.
I've been looking into Patreon, Ko-Fi, Payhip and Gumroad to be specific.
Anyway, my question is, if the platform is missing the Credit Card payment method, do I lose a percentage of customers/subscribers because they don't have Paypal and/or they don't want to use it?
And do you know what percentage...
