I've noticed monero guys funded (and will develop) atomic swaps feature, between monero blockchain and bitcoin blockchain.
That would be interesting as a feature to BiblePay.
Atomic swaps between BiblePay and Dash. There is now a feature where we can pay Dash with BBP but it requires a minimum amount of BBP coins. Atomic Swap would be nice, and should work for any number of coins (if that covers the network fee).
