Value is subjective. That fiat can be burned doesn't give it value. A twig on the ground has more utility in that regard. Crypto's intrinsic value is that it is safe from government and can be used anywhere in the world regardless of borders instantaneously without a middle man. There has never been a currency that offered so much freedom. What is your alternative? Gold? The government can and has confiscated that in the past. They can't confiscate the blockchain.
