I'm ignorant of this, but is a sell on clause only triggered if transfer is a larger dollar amount than what was sold prior? Is it 20% of money above 6MM? 20% of total just seems so high.
Can be either. Some transfers have a percentage of profit clause, some have a percentage of total fee clause, some have a percentage over a set fee (so like, 30% of anything over $5 million).
What Kaku's specific language is, we'll probably never know.
