Am I the one only who sees the fatal flaw in the system? The currency is based on the update of the ledger, which needs miners to keep getting updated. Miners are only doing it because right now, the value of bitcoin received by mining is greater than the cost of electricity needed to do the mining. But what happens when that is no longer true? Miners don't have an incentive to mine, the ledger stops being updated and the currency becomes worthless. It's inevitable.
