An invasion of Venezuela is unlikely, almost impossible. Americans only invade and attack countries in desperate conditions, with extremely weak armies and easily corruptible leaderships. This is not the case of Venezuela. They are trying to starve Venezuela but they didn't break it, they make people suffer, they fabricated an extreme social conflict based on hatred, they generated a disastrous decline in the economy but it's not enough. Petro is safe, in that sense. But with the whole western world against it.

The truth is that blockchain technology is not neutral. The myth of decentralisation can be demystified with the case of Petro: we all can see and imagine the difficulties to find support and collaboration around the world for this project, and we know the reasons. Just google "Venezuela Petro" and see the news Google filters for you.

If Petro succeeds, the success will be worth 100x any other coin. Basically a coin with embedded leverage.
