No, increasing demand for tokens will increase the price of the tokens thereby reducing the amount that is going to be burned for each transaction. In practice this will mean that we will not run out of tokens, just burn a decreasing amount of the issuance over time.
Here’s an example: if you pay for a $100 purchase with the Crypterium app, when CRPT is worth $0.5, you’d burn 1 token. But if the CRPT price increases, for example to $2, you’d only need to burn 0.25 CRPT for the same transaction. Simply put, the token-burning rate will be constantly decreasing. Think of it as an asymptote graph. Moreover, CRPT token is not an integer with 18 digits after the decimal point.
