I have been investing money as well as my friends money in some low risk high return cryptocurrency. It's been going well and calculating the percentages of return for each investor has been simple so far, however as it gains more and more money is being added it's starting to get a little more complicated.
So my questions are for clarification and discussion. 1. If a friend invests 20$ at 150$ Total Portfolio Value(TPV) making it 170$ he now has 8.5% stake, correct? 2. If same friend adds another 20$ once the portfolio doubles to 340$ he would only receive half the additional percentage increase? So 12.75% with 40$ total in at 340$ TPV? 3. This is the most brain racking question. So let's say we are at 400$ and a different friend adds 100$ so 500$ TPV. His percentage is 20% but this would also water down other friends 12.5% as well as my stake.
To summarize, the first two points I'm pretty sure about but could use an equation to get the same correct answer everytime and not rely on dummy math. The last point I know it will water down all existing stakes with new investor money I just need an equation.
