The report indicates that the annual consumption of power from Bitcoin mining is 8.27 terawatt-hours per year, and the global production of fiat currencies stands at 11 terawatt-hours per year.
Gold mining burns a staggering 132 terawatt-hours per year.

Worst of all is the ENVIRONMENTAL damage caused by the chemical spills from all mining including gold where mercury is used.  Most mining industries have tight standards in developed countries but the pollution left behind trapped in pits and lakes eventually fail and flow into the rivers and aquifers.  The damage is appalling!  In third world countries even children are exposed to mercury in the processes of gold extraction.



More info here:  https://www.smithsonianmag.com/science-nature/environmental-disaster-gold-industry-180949762/

Mercury is more of a third-world problem, while cyanide affects even first-world countries.

Welp, taking a vacation from cash trading since kraken is unusable. Withdrew all assets. Damn shame for everyone involved, but there we are.

I'm totally fucked at Coinbase. Sitting on an obscene amount of fiat from a recent sale, but don't have access to my Funding/Withdrawal page. Something 'tarded like below is what I'm getting.

Sheeeeeeit.



This a time delay exploit that the whales traders will be able to use again and again.

They will shake people out, and while their fiat cash out is trapped in limbo, the whales will be able to move the market back up and fiat sitting in limbo won't be able to get back in.

Fortunately Coinbase is not that big of a player compared to the global trading volume Tongue

and we dont know who have been pumping bitcoin recently. It could be hedge funds who are going to sell contracts in CME, and we dont know if the banksters who are against bitcoin will be their clients or not.

I think this was more or less settled (Koreans) ? Unless bankers and CME shorters would use the KRW markets with 2-4k premiums...

Yeah, ok but this is thug-style interrogation, not EU-like interrogation. I'm sure Bulgarians maybe more harsh, than say, French or Swedish interrogators, but still don't expect any violence Tongue

What I find odd in all these confiscation stories is the password protection of confiscated bitcoins. I mean ok, the authorities might have access to a wallet.dat which says it has XXXX bitcoins in it, but from there to actually accessing the funds is quite some distance away - assuming there is a wallet key protecting the funds.

That's why I'm assuming that most authorities' "confiscations" do not necessarily translate to getting access to those coins.


But dont they interrogate the guys who are arrested?


And they have to give the password? Why?

http://www.zerohedge.com/news/2017-12-08/bulgaria-government-shocked-discover-it-owns-3-billion-bitcoin

Ain't seen any mention of this. The Bulgarian authorities seized 213,000 bitcoins from some pesky criminals. I wonder how and where and over how long they gathered so many coins.

No doubt some pencil necks will insist they will dump all on Yobit.

In such cases of confiscating bitcoins, the effect on the market is actually the opposite of what is described or implied (dumping): More btc removed from circulation as no-one has access to it (not the criminals who know the password but don't have the wallet, nor the government who has the wallet but doesn't know the password).

Why there is only an asm version of the fe_mul and not of the fe_add too?

From what I've seen in profiling, fe_add is rarely the bottleneck, so probably that's the reason. It's too small. It should also be able to compile depending the available hardware and get sse/avx speedup by doing multiple adds per instruction.

Quote
I'd like to know besides if someone know if it is possible to exploit avx instructions to speedup operations with 64 bit representation.

The main issue with avx is the lack of 128 bit multiplication and 128 bit addition.

That's not a problem though for the 32 bit field because there are 64 bit muls/adds (which can be handled). In theory you could do up to 8/16 32bit field results in parallel on the same thread with avx2/512 - and go much faster than the 64 bit, but that requires rewrite of all peripheral code because you need to feed it multiple "a" and "b" to get multiple "r" - which of course have to be used by other functions beyond mul/sqr, etc - which would also need to work in a stream-like fashion that deal with multiple inputs/outputs instead of one.

(My focus has been on using avx2/512 on a single 32-bit field result (one a, one b, one r) to get it faster, which avoids the rewrite part - and since the code after the multiplications and additions is more sequential it fails to produce much of a speedup. However proper speedup of avx2/512 is dependent on using multiple "streams" of inputs and outputs).

Back from '14 and my 18k USD dream (came true yesterday in terms of price, albeit 11 months off in terms of date - which is a half-failed prediction):



I've actually dreamed of btc and darkcoin (back in the DRK days, not as DASH).

BTC I've had only one dream:

Price prediction based on a dream: 18.000$ in 2016. Posted for future reference Cool

What model is this based on?
I would sell 10% at that point  Smiley

All you need to hit a right prediction is to make many of them at random. Then, once one hit, you point to it and say-aha!
This is the method that many economists are using or so it seems...

As I said, it is info from a dream. In the dream I was having a conversation with someone (the sense was that he was quite knowledgeable) and apparently I was asking him about future bitcoin price. The answer he gave me was $18.000 / 2016. Whether it is true or not, we'll have to wait and see. That would exceed 250bn usd in marketcap which I find hard, but then again, it's still a marketcap lower than some companies.

Darkcoin was trading related, I actually saw exact prices of pumps and dumps. I had success more often than not.

The recipe for dreaming such stuff comprises of 3 ingredients

1) Obsession or too-many-hours dealing with something in daytime
2) Thinking about the same thing before going to sleep
3) Being able to suspend one's ego-facade. It seems to interfere with intuition.



...now around September this year (2017) I saw a new BTC-related dream: 63k ...no date given. In the dream I was looking at the price on my screen. I also have the impression from the dream, that price first went to 0, then to 63k. Now zero is impossible (with 0.01$ you can buy all bitcoins? lol) so it seems absurd as a notion so when I woke up I interpreted it as something fork-related... (the s2x was still looming back then). Yet that didn't even materialize, so... who knows.... we'll see.

We will need some time until we break this new GDAX ATH (19.7k)

There was a chart a week ago, or more, which showed 22k on December - based on long term extrapolations. It got attention because it predicted november price but december seemed "far fetched" for most at the time. Now it seems pretty doable.
