I have not connected my PayPal account and bank acount to fiverr .can people still order my gig from this option
People order your gig with their own Paypal or bank accounts, not with yours.
If you connect your own Paypal/bank account to your fiverr account, you will then have the possibility of withdrawing the gig money you earn into your connected paypal/bank.
But until you connect those, people will still order your gigs and the money you earn will be deposited into your fiverr account until you connect any of the previous.
For helping me
