This cannot be understated enough. Accepting cryptocurrency may hit you with KYC requirements in your region, PayPal is frankly worse than Stripe, opening a merchant bank account just to process might not be worth it, and oh PCI-DSS audits will just kill your idea off the ground of processing credit card payments, not to mention the hassle of actually handling the fallout of card data leak. If you're not in the US and will only process domestic transactions are are willing to skip acceptance of credit cards, you would want to look if your environment allows a much more simpler acceptance system (for example in Canada, parts of Europe and India a merchant bank account is relatively frictionless compared to American ones). Otherwise, read on. Unless you're a very big company with dedicated accountants and backend logistics and in the fees collected by Stripe will be bigger than bringing it inhouse, it'll be much, much more expensive to be honest. Stripe probably is the least worst option right now since that you don't need to have a merchant bank account for example, which can be an headache. However, if you want to minimise data collection at any cost, then probably only accept cash and cryptocurrencies (that is, if you run a node and not outsource it a la Stripe)?
