User's share from each invesment equals to user's assets divided to all other user's assets, 1 asset equals to 1 BTC. Thus when a user buys 1 asset for 1 BTC when all assets equals to 3 then all assets becomes 4. The invested bitcoin divides between all users according to their shares. After that the share of the user becomes 25%. That means that the user will get 25% of the further investment then shares of each user recalculates. Received funds could be reinvested or instantly withdrawn.
Wouldn't this just mean if you, at the time, invest one bitcoin and have a 25% share of the "assets", and then someone else invests 1 BTC, your percentage of the assets would go down to 20%, staying at one bitcoin. I don't understand where the profits come from.
