Bad bad credit: beware of this platform

I invested using the platform, financing loans from all over the world. I used the autoinvest option, and gave loans to borrowers with rating from B to D. More than 70% of my USD loans, more than 50% of my EUR loans and more than 90% of my BTC loans are defaulted. I don't see ANY debt collection anywhere around here. My average IRR seems to be worse than -30%. Don't invest in this sort of thing.
