why is the years that the rich get richer and the poor become poorer and more oppressed?
What do you think should be done to keep this economic gap from continuing?

I still do not understand why the US does that, Iran is one of the largest oil producing countries in the world. The US should not interfere with the bilateral relations between the countries.

Do oil prices impact the price of bitcoin? Off the top of my head, the answer is: no. 

The price of oil can affect shipping and transportation of goods/services/employees. Bitcoin is a truly global enterprise and isn't reliant upon transportation nor regional/geographic base. It won't be impacted by fluctuations in crude value.

The second potential way oil could affect crypto is in cases where the value of crude were linked to the price of electricity production. Most industrial bitcoin mining operations are powered by hydroelectrically generated power which is far cheaper and more environmentally friendly than hydrocarbon based energy sources like coal or oil. The price of oil won't impact bitcoin here, either.

If residents spend less on fuel, they could have more liquidity to buy crypto. That's the main scenario where reduced oil and fuel prices might affect bitcoin prices, off the top of my head.

Maybe people tend to buy more crypto because they have a lot of savings from oils for their cars. But I'm not so sure about that. As long as crypto is going well, then I support it.
