It is claimed that Satoshi Nakamoto owns around 1 million bitcoins and he mined them when mining bitcoins was easy ("premine").
We all know that is not one person and that they hodl this to ensure that there is one entity to have enough to make sure they have enough coins so if there will be whales they are the biggest. BTC is just an art-project which became a really good one for everybody. No premine at all, just common sense.
