Good luck NotATether, hope my error didn't cost you too much time.
I'll definitely share the reason for this experiment and I'll definitely do it here first, but not just yet. I need this to run for a bit first to prove how secure or otherwise a completely exposed but randomised key is
Anyone saying it's easy and so redundant, great help yourself to the BTC and prove how easy this was all along.
I'm offline till the morning so I'm afraid I'll be quiet until then but happy to respond to any feedback when I get back
