Swami Shivananda once answered this question wisely.

Why has God created the world?

[...] Creation of the world has a purpose. Just as we cannot have a sun without rays, similarly, we cannot have God without the world process. The world is like His rays. It is His Svabhava, nature. Just as a juggler produces something and makes it disappear, so also, God produces this world and makes it disappear. God is omnipotent. To ask why He created the world is an Ati-prasna, a transcendental question. We will be only wasting time by discussing it. Before asking about the world, ask about yourself. Know who you are. Then you will know everything.

The Sanskrit word *ati* means "too much" or "too intense" and *prashna* means "question" or "matter of dispute."

The amount of questions the TO has seems to prove Shivananda's point, doesn't it? When a person has so many transcendental questions this person becomes confused. This is good, because this person is a seeker. Seeking is really a state of confusion. 

When you are seeking concentrate on the search, or more funny questions will arise you cannot answer. Maybe people get angry about your questions (or answers) which then causes non-funny problems.  In the end you will have wasted time, maybe lifetimes, and eventually forgot what was it you were looking for.

So let's concentrate on what you can do.

If we can't answer the question why God has created the world we already live on, how can we ask the question what God is? If we cannot answer the question how such a vivid image of the world appears within us, from a few electric impulses caused by our senses, how can we ask the question what God is?

Don't try to begin with such questions. Answers will be revealed to you in form of grace; don't worry! Concentrate on what you have already experienced. In other words, just try to find a clear, simple start to begin your [spiritual] path.

Surprisingly this is super-easy. We find real truth in ourselves anywhere and anytime. Whatever you as a person experience you will perceive as truth. Pain, love, awareness, realization or even inspiration. Whatever it is, nobody can talk it out of you, because it happened within you. Isn't it so?

Truth has this astonishing property: once seen it can't be ignored. You have become *aware* of it. Therefore it will begin to work with you. Now use the great gift animals don't have: the ability of self-observation.

But there are so many things you experience, right? Some of them you like to repeat, some most definitely not, and some even [partly] contradict each other. How can this all be true? Ati-prashna seems to be inevitable.

Try to begin as humble as you can. Try to see how wonderful your life actually is. Try to see how God manifests in other human beings. Try to see how God is manifesting constantly as the best parts of our civilization.

When you do this without hoping to win something (just control your ego as best as you can) grace will come.

Seems unlikely. The Lightning-Network already applies Milli-Satoshis (msat). A thousandth of a satoshi. They are rounded to the nearest Satoshi when a channel is closed. Correct me, but AFAIK until then many transactions can happen between two parties.

However, 1 Sat == 1$ would mean that all BTC are worth roughly 21 * 10^6 * 10^8 =~ trillions of dollars. How can this ever become true? And what would a dollar be worth then? At least the price of Lambos will go through the roof... 

IMHO the Dollar and the Euro (and thus all other currencies) will already begin to tumble when 1 BTC comes close to 100.000 $.

Then currencies slowly will become... something else. Like so many I believe currencies in the present shape have no future. For me it is a dangerous perversion of the current monetary system, that individuals can own hundreds of millions, and do nothing useful with it, while so many people cannot pay for medicine, rent or healthy food.

I think that if you are crypto-rich in the future, whether you like it or not, you will have to take responsibility for the society and the environment you live in. In other words, take your cryptos, bring the right people together, take those sick Dollars and Euros out of the equation and people will do wonders. I strongly believe that. Anything that has gone wrong on this planet can be healed on this planet, isn't it so?

In short, who wants to live in a world where dollars and euros are still dominant and 1 Sat == 1 $?
