I've had the reservations between the vast opportunities that the blockchain technology presents us nowadays but at the same time the immutable ledger that it contains. The people are the ones that get screwed because we are using it; the big businesses and politicians aren't going to be the ones using it so we can track their transactions. The privacy coins and decentralized exchanges are going to be fought tooth and nail by the powers that be but I think we can overcome that because we are many more than they and that comes with a big advantage.
