2) Paypal and bitcoin don't work well. Just a lot of scammers if you trade BTC for paypal. But no you can't put into paypal you would have to use a 3rd party to get paypal money for them and it's risky. I highly suggest using a exchange linked to a checking account instead of paypal.
I just want to pop in for a quick second and mention that it's also technically against the PayPal ToS to buy/sell bitcoins with PayPal funds. That's why chargebacks against bitcoins always work, and also why PayPal and bitcoins don't mix.
You could always do a bank transfer for the bitcoins, and then connect your bank to PayPal and use the funds from there.
@OP, you might want to close this thread now that it's answered. (It's on the bottom left.)
