It’s just the same thing as a take profit in the stock market. Intellectually it seems reasonable but because a lot of the bets go straight down (never raise another round for that take profit opportunity) you need a higher multiple of the ones that win.

You end up taking profit at a 1.1 return and in 10 years it ends up being uber.

Positive skew strategies (lose a little on a lot of bets and win big on a few) are impossible to use take profits on because you need those big winners.
