but not because the tokens run out. Towards the end of the coin supply, the price of coins will simply rise higher and higher, so
the amount of BTC needed to buy the last coins will go up all the time.
Look even at the market spread today: there are 10.4 GAM offered for 1 BTC *each* !!!
If we really get down to the last few GAM, don't you think that they will continue to go up in price,
so that the last GAM will never ever sell to be burned, it will be ever smaller fractions and the price of GAM will continue to go up with it becoming more and more rare. No, there is no need to do anything else when we are nearing the end - the end will simply move away, this is a self-balancing system and it will work great.
