I have received the collateral.
Sold 6k XLM at 0.0000065 a piece and got 0.03892135 BTC.
Sold 50k BCN at 0.00000005 a piece and got 0.002495 BTC.
I got a total of 0.04141635 BTC from this when there was 0.0631836 BTC left until the principal was paid (so not even counting interest).
I lost money because Max ditched his devalued collateral, and I am making a note of it here because this loan has come to a conclusion - that conclusion being a default. Hopefully he will come back and make it right at some point but I'm not holding my breath.
Thanks for reading,
Hatcher
