> It is even worse than Gold because you can't just hold when market crash. Could you elaborate?
What good are your altcoins when the developers/miners give up on the project? A bar of gold is always a bar of gold, no matter what the price of gold is.

NVidia actually consumes less power in most games. But AMD cards use less power with integer performance.
This is the reason, Nvidia is good for floating point. Which is why people use them for deep learning.
On the other hand they would have a self interest to preserve the system, if trust in cryptocurrencies collapses then the big miners would have a lot to loose.
This just sounds grandiose but really, renting a 747-400F is not such a big deal. This http://www.opshots.net/2015/04/aircraft-operating-series-air... article gives a figure of 24-27000 USD an hour. You need it how long? Ten hours? Twelve? Using a random card Amazon gives us a box size of 13.4 x 9.5 x 3.1 about 400 cubic inches. Say http://www.cargolux.com/our-expertise/cargo-equipment/aircra... we have 21 347 ft^3 t…
A side business I run supplied them with components in 2016. Based on what I shipped them I'd say they deployed some where in the neighborhood of 18,000 graphics cards in 2016 and they were supposedly ramping up to go even bigger in 2017. I don't have any insight into what they are currently up to because that scaling apparently involved hiring a eastern European engineer on the cheap to masquerade as a customer to t…
Sounds like an interesting story here. How did you out him/her?
This is a gold rush[1]. People that were early in BitCoin already cashed, now profit is made on exchanges and by hardware suppliers. It is even worse than Gold because you can't just hold when market crash. https://en.wikipedia.org/wiki/California_Gold_Rush
People who bought at the absolute peak of the last market, where it was for only an hour or so, are now up %2700 on that purchase in 4 years. You can hold and you can dollar cost average, and if you weren't buying with the intention of holding for 5 or more years you weren't really investing you were speculating and if you're speculating you should be hedged or have a strategy that can handle a dynamic market. I know…
These headlines are annoying and what I consider to be "fake news". -- EG They are blowing up some factoid or partial fact to make a false impression. Here's the reality-- -- Ethereum is going to PoS soon. Even if it doesn't fully switchover it will decline in profitability for miners quite a bit. -- Ethereum is down %50 in the past couple weeks. The GPU boom is over (for now) and supply should be loosening. -- There…
Is this the real story behind nVidia's insane stock spike over the last year?

Apparently they are going to bundle most of them with games and hardware discounts initially, to discourage buy ups by the miners.

The RX Vega 56 part has 50% higher SP compute per watt than the RX 580 and 570 (50 SP GFLOP/watt), and is only $399 MSRP.

Going to go out on a limb here and predict credit cards have a better $/watt ratio than bitcoin.
According to a recent estimate, ~4000 times more energy intensive. It’s an incredible waste of resources for most current use cases. https://motherboard.vice.com/en_us/article/ypkp3y/bitcoin-is...
Further, the cost per transaction in bitcoin a year from now will be about 1,000,000 times lower due to Lightening Network.
I know there's a political desire to demonize bitcoin (this is vice, not exactly an objective source) and that ignoring one side of the equation to try and make bitcoin out to be an environmental evil seems the best approach you can get but its' absurd on its face.
i wonder if these massive mining operations have enough power to cheat the system: couldn't they quickly compute a series of valid blocks with the cheated transaction if they band together? the longer chain of blocks would win against a shorter one. On the other hand they would have a self interest to preserve the system, if trust in cryptocurrencies collapses then the big miners would have a lot to loose.
But that' d knee cap the value of the currency. Which in turn would nuke their profits and render their capital outlays useless.
