I stopped accepting PayPal for a few reasons, including lack of security, such as my account being hacked, but not because of the fees. I just straight up don't like the service anymore. I know for a fact that has cost me sales since people are so used to paying with it but that's a gamble I've taken. I do accept Venmo and Zelle and have had great success with using those services as a buyer and seller. The occasional check too.
With all that said, a new seller here may have no choice but to accept PayPal due to the buyer protection it offers.
