I don't think so because all conis received by paypal will be converted to fiat directly.
I haven't seen the details of paypal's charging structure for BTC use, but if it's cheaper than regular paypal, the demand I believe will outstrip the dumping and a price rise will ensue.
Perhaps the bigger eventual benefit though is in raised public awareness - paypal are playing with fire here, a lot of people hate them but aren't aware of any alternative - that's about to change, and again, IMO this will push BTC price up through increased demand.
a highly volatile currency they will charge a fat fee.
If you want to trasfer currency international for example from europe to australia buy btc with € transfer on zero fee and convert in AU$, no need to pay 5-10% fee to paypal
