Hereās some information regarding payment processing on Ribblr. It also has a link to Stripeās fees as well as their terms and conditions
I havenāt had any problem using Stripe. You do have to enter in email, name, address, etc when you sign up but I donāt recall it getting as personal as a social security number like paypal does. You do need to add a bank account for them to process payments to.
As far as whether its worth it, I donāt see why not. Thereās no fees unless you make a sale or get tips, so there is really no downside other than the time needed to set the whole thing up
Edit: also hereās Stripeās FAQ page for pricing. They have other links at the bottom that might help answer your questions as well.
