There must be a crypto betting market out there where you could create a "Journalist will not be rescued from Belarus" bet and people could start betting against it until it became profitable enough for a mercenary company to do it.
I've seen crypto betting markets [1] that have bets on whether or not Joe Biden will still be President at the end of the month. Ostensibly they are about his old age or Trump proving the election fraudulent or some such. But another way to construe them is as an inducement towards assassination.
