Namworld's BTC-Bond on BTC-TC. That only pays 0.03% per day (.21% per week, not much over 10% per year) - so I've been reluctant to propose it as it's so low and I can't anywhere find details of what assets currently back it.
That does seem kind of low, especially if there's no backing information. I'd be more open to LTC-ATF.B2 if there was more than 50BTC opportunity to invest in it.
I would like for DMS.SELLING to invest a bit more, either in J-D, CL, or another avenue - I like the idea of secured loans as long as they're not too much trouble for you to set up and maintain.
