Actually I think he made a mistake. Getting 3.5% risk free ( unless you think usagi will default) is one of the best deals there are today... just because there is the word pirate behind the deal is not a very good reason....
If my investors don't want it, I don't do it. Simple as that. They have their reasons: mainly, they already have plenty of pirate exposure, and thus are seeking an investment with a return that is wholly independent of pirate's operations.
That said, anyone else should probably take this deal... esp when you can borrow at 1% and then get insurance on top - it's like printing money. But that makes me wary, because the same amount of risk is still there, it's just systemic instead of concentrated.
It's not really printing money, since... well, CPA is taking the full risk for a fraction of interest, so that money comes from somewhere, even if it's well hidden.
But since CPA are apparently willing to play Santa here, I'd really like to see that concept applied more often (and have a second chance to jump on something like Yarr when insurance is still full!).
Even besides from Pirate, there is no scarcity of high-yelding, but shady ventures on the Glbse; for instance Obsi's "high risk passtrough" (to some undisclosed real business, not Pirate); also for TEEK.B there is demand for insurance (someone created HEDGE shares for it, to provide covering to some extent).
It would be firstly in CPA's best interest to get the opportunity to apply fairly high fees, but differentiating the risk.
