1 BTC and paying with PayPal and this is your very first post. I doubt very much  it will happen.

PayPal is notoriously reversible and a very high risk payment method. Even established members here struggle to buy far less than 1 BTC.

Verifying identity and legitimacy hardly helps as there are scammers here who do the same thing for a mere few cents.

Escrows will rarely or not accept transactions if they detect a high risk of a payment recall or reversal.

Chargeback privileges end after 180 days and only then will one feel a perceived sense of safety in sending bitcoins.
