There is not really anything to fear. I've been using paypal for years now and the account is as strong as your password basically. It's not as "safe" as regular online banking because the pin doesn't change but it's safe enough.
Honestly I don't get the fear. There are so many safe guards in place nowadays that it's next to impossible to lose money involuntarily. I don't know an online payment system where it's not possible to just have stolen amount be returned. So in this case you even have 2 safe guards. You have the ability to just get your money back from either Paypal or your bank. There is also a partner program with Google where it sets itself as another safeguard on certified shops. You really have to fuck up really bad and do nothing about it to actually lose money.
Paypal is connected to your bank account and will automatically book the amount you paid online from it. The good thing is that it works instantly. It pays the amount and then later books it as soon as possible.That way you have the benefit of a credit card without using a credit card. However some shops may add a "tax" if you choose paypal as payment option.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
