It's the same problem for all coins, litecoin, ppcoin, namecoin etc...
There are too many coins and not enough investors.
That's why a voting system was created. If you think there are too many mined coins, the community can use the voting to change the block reward. It's much better to control the money supply.
Well this is a great idea and ideally it should work, BUT that would be the case if you have a huge community and hundreds of people voting. This way you can counter the people that try to manipulate the supply/price/market. Right now all the people that wanna manipulate vote all the time and the rest of the people vote whenever they remember.
So well, lets do something to grow the community and coin acceptance so we can get that working
I guess a good idea would be to finish the message system
How is manipulation possible? The manipulators will lose a lot of money because the voting system is not free, it requires 5 TAC / vote and 10 votes minimum are necessary.
