Wanted to point to the startup the author seems to be running, which is to sell insurance somehow tied to Bitcoin: https://meanwhile.bm/

For the record, that strikes me as seriously improper. Life insurance is a heavily regulated offering intended to provide security to families. It is the opposite of bitcoin, which is a highly speculative investment asset. Those two things should not be mixed.

Also, the fact that the disclosure seems to limit sales to being only occurring in Bermuda seems intentional. I suspect that this product would be highly illegal in most if not all US states, so they must offer this only for sale in Bermuda to avoid that issue.
