Hey I'm looking in to trying bull BTC.  Can you help with a couple questions?

1)Do you use a one time email address for this ? 
2) do you need a phone to sign up non KYC ? Did you use your regular phone or burner?
3) What do the fees end up being? I find the only issue with bisq is typically have to pay 2-5% above current mkt price.  Does bull BTC add 3% to their BTC mkt price ? 

Thank you!!!
