However it's possible that we won't be alive when Bitcoin reaches 21 million and is fully mined. Who would have known it would exist before then? We are unable to make accurate predictions, not even knowing if we will survive. But if Bitcoin is still around by then, I have no doubt that its value will skyrocket. Miners will always support Bitcoin since they will continue to profit from transaction fees. When the number of Bitcoins reaches 21 million, the price will be very high.
