I don't really care about using PayPal. Privacy is important to me, especially when it comes to crypto. I would never want my government to know that I am a crypto user and that I have an important asset like Bitcoin. Even paying with Bitcoin is very annoying for me, I would definitely prefer a decentralized wallet as an online payment for private purchases. The main purpose of crypto is privacy and decentralization, so why would I use a decentralized currency in a centralized way when it is not private at all? It doesn't make sense to me.
