Want to buy 0.3 BTC with paypal. I understand it's paypal so I can do holding days with an escrow.
You'd probably have to wait a significant amount of time if people want to hold on to their money via waiting for the dispute period to end, and even then you can still scam via claiming a hacked account for a chargeback. Honestly, I'd think you'd have better luck with either smaller amounts initially or trying something like localbitcoins.
