Studies from Princeton and Cornell found that current rules governing the mining of bitcoins leave room for cheats or encourage behavior that could destabilize the currency. Such changes could be difficult to implement, given the fact Bitcoin — by design — lacks any central authority." The main problem discovered is that transaction fees do not provide enough incentive to continue operating as "miner" after there are no more bitcoins left to be mined.
