Part of what is said by taseenb is right but unfortunately much is wrong or misleading and simply reflects the official propaganda around the petro. Only a few examples:
Petro ($PTR) will be a sovereign crypto asset backed by oil assets and issued by the Venezuelan State.
El Petro will not be backed by oil assets as is made clear by the white paper. There is no mechanism at all by which a holder of petros will be able to successfully claim oil assets or their value from the Venezuelan state.
That phrase is copied from the White Paper. You are wrong, $PTR is backed by oil assets and will be exchanged by its value in Bolivares. The mechanism is not in place yet, simply because the Petro is not even active yet.
You indeed copied the phrase from the white paper. That doesn't make it true. As I said: You are spreading the official propaganda around the petro. That it is supposedly backed by oil assests is central part of this propaganda. Only that the white paper shows it isn't. That the mechanism isn't in place yet is not the problem. The problem is that there is no mechanism foreseen. If there was going to be one it would have been the task of the white paper to describe it. There is none and there won't be one.
