Mortgage-backed securities issued by private issuers, whether or not such obligations are subject to guarantees by the private issuer, may entail greater risk than obligations directly or indirectly guaranteed by the U.S. government. The average life of a mortgage-backed security is likely to be substantially shorter than the original maturity of the mortgage pools underlying the securities. Prepayments of principal by mortgagors and mortgage foreclosures will usually result in the return of the greater part of principal invested far in advance of the maturity of the mortgages in the pool.
Look, you and I are sophisticated, and we get that "bitcoin's price increase is deflationary and makes it a bad currency" is not a good argument against bitcoin, because "bitcoin is a bad currency" is not a good argument against bitcoin. (People keep making it though.) Bitcoin's value proposition -- much like that of gold -- is that it is an uncorrelated store of value, not that it is useful for buying a sandwich.

"Cryptocurrency-financed warehouse lending" has the word "cryptocurrency" in it, so it's worth billions of dollars, but I'm not sure it works as a business model.
BB, B, CCC, CC, and C – Obligations rated ‘BB’, ‘B’, ‘CCC’, ‘CC’, and ‘C’ are regarded as having significant speculative characteristics. ‘BB’ indicates the least degree of speculation and ‘C’ the highest.

!! WARNING !!! Note that on CryptoFacilities each contract is denominated by 1 BTC. So if you bought a fraction of BTC you can NOT perform a perfect hedge of the value.
