They own i think almost 10%, but after more times passes they will own much more if they will buy, maybe after years pass they will own almost 20% or something close, but this depends how much cost bitcoin when they buy.
They would like to own as much as possible or for that matter anybody who know and believes in this would like to buy at this price point as it’s very low and want to make the best gain for their future which crypto coins will provide in coming years
