Well, I don't use PayPal, Infact PayPal isn't available in my country, I've always traded in-wallet using trust wallet and I've never had issues, this is why decentralization is so so important, PayPal is a centralized company running a centralized wallet, theres no way you would perform in-wallet trades with them without encountering an issue on one of the days you trade, so it's better to chose decentralized wallet if you wanna perform in-wallet trades.
