I have a balance of Bitcoins in my ripplepay classic account, how can I move that out of there and into a Bitcoin wallet?
Classic.ripplepay.com did/does not have gateways, only interpersonal trust lines. The easiest would be to contact one or more of your ripplepay contacts that owe you bitcoin (or one of their contacts) and ask them to send you bitcoin in exchange for a ripplepay payment. Depending on your connections you may be able to zero your balance with only a single transaction even if you have multiple trust line balances.
Another option would be to use the services of
Ripple Union, however, they usually only deal in CAD.
