I wonder how that would affect things. The average person would not like some dude owning 25% of the supply.
Even the rich people who let's say can afford to buy, but I doubt they will risk their money for that big supply in bitcoin knowing that's a risky investment.
On the contrary some average dude would love to see something like that to happen, why? Because he knows that the price will pick up, his portfolio grows and everyone is happy. On the downside, he can be a big player, a whale than can manipulated the price in his favor. If might not be that easy to do, but having such enormous amount of Bitcoin is definitely a plus for him.
Those whales has deep pocket, and I'm sure they own their money through investments so they definitely will factor in the risk, if ever they wanted to join the fun in this market.
