From my experience of using Paypal, safest way to use Paypal is to not keep any credit inside.
Don't link an actual debit/credit card to it.
Use prepaid credit card/debit card and link it to your Paypal to activate.
8 years back I used this

but nowadays you can use this prepaid credit card
Shell easiGO American Express cardNeed some credit in it to activate your account if you haven't already. After you activate the card, use the balance and keep the card empty.
You can transfer funds from and to Paypal if you have a RHB savings account, so go and make one, it only takes a few minutes in the branch, register for RHBNow ebanking and you can topup your Paypal using your RHB account.
If you want to pay USD 200, then you topup USD 200 into your Paypal.
That way, even if your Paypal got hacked, nothing will be lost.
