I'm mean it's easy decision for them, they have been in the game for so long, this family is on the business of money making and we all know that in Bitcoin, if you learn to invest early and then just hold, your money will grow.
So I'm not surprised by it, this is the new era, and the sooner they got the better for them and for the market in general. And even if they have poured a lot of money here, I doubt that they can manipulate an inch of the market in their favor. Everyone here is seriously for the money so it doesn't matter if you are a average joe or whales like this traditional family.
