I dont understand , Can you explain this Mathematically Constrained Supply
After the token sale, token supply is constrained mathematically through the programmatic algorithms used to determine price.
Think about it like this:
1) Someone buys 1 ETH of tokens over, and over, and over, etc...
2) Every time they buy, the number of tokens they get becomes smaller, and smaller, and smaller, etc.
3) During each buy, the average price per token goes up.
4) Eventually, the number of tokens that person get becomes approximately 0, and the price becomes roughly infinite.
So, at some point, the repeated 1 ETH transactions create approximately 0 new tokens, which means the supply (although technically infinite) will be mathematically constrained. I think this is graphed in the whitepaper a bit, illustrating that the economy as described would be very, very unlikely to increase in supply more than 50%. And, if it ever did reach this point, it's because a tremendous number of token purchases occurred, which would (in theory) push the price up significantly in the process.
