His company is buying aggressively not just to grow its portfolio but because it believes (and it does very well) that the price will rise to such an extent that by selling a smaller number of BTCs it will pay for the fiat bonds/ securities/ loans. This means that it will pay less and will still have a significant number of BTCs to move forward without any burden. From what I know, he owns (as an individual) a significant number of BTCs, close to 18000BTC and that makes him already a strong holder and BTC supporter. So, I doubt that he and his company will stop buying. The thing is when he will stop doing it aggressively? Or he won't stop doing it?
