There is no prohibition against POTUS "doing business" while in office. There never has been. My guess is that there never will be either.
Article II, Section 1, Clause 7 of the US constitution would disagree with this assertion
The President shall, at stated Times, receive for his Services, a Compensation, which shall neither be encreased nor diminished during the Period for which he shall have been elected, and he shall not receive within that Period any other Emolument from the United States, or any of them.
It is unclear to me how any arbitration clause in a phone app's click-through terms and conditions could possibly supersede the Bill of Rights, specifically the Seventh Amendment:
In Suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved, and no fact tried by a jury, shall be otherwise re-examined in any Court of the United States, than according to the rules of the common law.
Any lawyers here who could explain the legal basis for Uber's case here?
The 7th amendment states that in civil cases, your right to a jury is preserved. By signing an agreement with an arbitration clause, you are waiving your right to bring a lawsuit in the first place. There is nothing in the Constitution that preserves your right to bring a case.
From what I can see, 3879 BTC has hovered between about 50 million and 64 million in the past few months. It's still a lot of money, but makes you wonder where the rest of it is. Probably lost in journalistic best intentions...
Your numbers are off, 1BTC valued at about $49,000 on Coinbase as of this posting, and that's actually down from recent highs of over $60,000. 3879 X $49,000 is about $190,000,000 at current market prices. If anything Sony has gained money from this attempted theft.
So I don't think that comics are dying per se, just like how radio didn't completely destroy the written medium, or video games destroy television. It's a different form of entertainment and has it's own strengths and weaknesses just like any other.
This is a solved problem that's in a transition phase. The world didn't get rid of all it's incandescent light bulbs for CFLs and LEDs overnight either.
Current 'proof of work' style cryptocurrencies are going to lose out long term to alternative validation methods like proof of stake. While the electricity cost of PoS block generation isn't zero, it's a far cry from current PoW mining. Conservative estimates say that the eventual switch of ethereum to PoS will reduce the electricity costs of block validation by over 99%.
There's also a lot of interest in crypto in parts of the world that don't have access to traditional banking. And smart contracts give Ethereum a lot of potential uses.
Is there a lot of speculation still going on with crypto; sure. Is it possible that the value of Bitcoin drops significantly, maybe even to zero? Absolutely. But cryptocurrencies in some form or fashion are undoubtedly here to stay.
They are actually making both kind of GPUs for different markets.
The crypto-only GPUs are made with the video-out portion fused off, probably because it did not pass testing. NVIDIA would have trashed such chips if they hadn't been able to sell them to "miners".
Technically NVIDIA doesn't manufacture chips at all; they're an R&D company. They produce the designs and outsource the actual production.
