Nice proposal.
So this would enable anyone holding nubits on Android to pay someone only accepting bicoins.
That could be indeed the first working use case of crypto-currency: Mixing the stability of NuBits with the adoption of Bitcoin.
However I am wondering why this time it would cost 4 times more than last grant (developing the single Android wallet).
Does it mean that the work is 4 times more complex or time consuming. Sorry just checking.
It seems that the release would take roughly 6 months.
6 months could be a long time in crypto world but at the same time, given the low buy liquidity right now, it would be problematic if the whole 22,500 nbt were exchanged for bitcoins immediately upon receipt.
Fortunately the upfront money is also half or 11, 250 nbt.
