I believe in PayPal, even though this is still an early stage, to anticipate big losses is not to buy a large amount of Bitcoin on PayPal. We don't invest Bitcoin in PayPal, if you want to buy Bitcoin in large quantities, there is a safer place than a company that recently adopted Bitcoin.
PayPal provides solutions to us as the OP describes
we all know and need to accept the fact that we cant use bitcoin everywhere
with paypal adoption bitcoin have a higher chance of merchant accepting bitcoin independently
