I honestly don't see any connection to Bitcoin in this case, and if the prices of both responded similarly in some ways previously, it's likely coincidence. I might have missed something fundamentally, but that's my opinion.
PetroCoin (MaduroCoin) however will benefit from an increasing oil price, so I assume that the investors and backers of this governmental garbage will happily look forward to what the future brings.
I'm interested in reading your theory. If it's convincing and makes me look at the situation differently in terms of Bitcoin, I will Merit your theory.
It is obvious that there may be no relationship between bitcoin price and petroleum price, But if we look at it critically with blockchain eye, petroleum blockcain based project like the one you just mentioned can be a mediating factor between bitcoin and petroleum price. Just have it in mind that bitcoin and blockchain in totality will soon control all other sectors of our global economy.
