It will likely happen prior to the middle of July. Lots of efficient mining gear is coming out, although the rate of manufacture is unknown.

I propose we lock this thread until such time as masterluc's return and only allow one post a year on August 14 (masterluc's registration date), in the style of the Poe Toaster who left a bottle of cognac and three roses on Edgar Allen Poe's grave each year on his birthday.


masterluc -- we hardly knew ye...

Ahhh, so close! Well that was fun.
184  Bitcoin / Bitcoin Discussion / Re: Many web wallets/exchanges only use an 80 bit shared secret for time-based 2FA on: December 07, 2015, 11:35:09 AM
Could the 2FA secret be calculated in a realistic time frame on those exchanges using 80 bit?
Depends how much money someone is willing to invest, but that number comes down every year.
185  Bitcoin / Bitcoin Discussion / Many web wallets/exchanges only use an 80 bit shared secret for time-based 2FA on: December 07, 2015, 06:10:52 AM
I took a look at the length of the shared secret, K, provided by the services listed below. They use the time-based OTP algorithm, RFC 6238. The HMAC-based OTP algorithm, RFC 4226, requires a 128 bit key and recommends a 160 bit key. RFC 6238 makes no such recommendation, although Google uses 160 bit and Amazon uses 320 bit for their own services. This is not an immediate practical issue, but these services should increase key lengths and be careful about using defaults.

320 bit
Amazon

256 bit
BTC-E

160 bit
Google
CEX.IO

120 bit
Kraken

80 bit
Coinbase
Bitstamp
Bitfinex
Poloniex
Purse
LocalBitcoins
OKCoin

I was contacted about this thread by our mutual friend DP. Can you paste email headers of the supposedly spoofed emails? We can see if they were spoofed or not. Of course they could have made them appear spoofed to engage in this fraud.

This is the kind of insane pump we should be selling. Innit?

Short term trader in me says yes. Degenerate moon kid in me says "Are you crazy?"
One day the moon kids will rule the world.

A rollover would be fun but I must admit I want an 8.4 as I never played this game before. Smiley How is the prize determined?

if your pick is 8.4  you get all numbers from 8.40 to 8.49  we use www.bitcoinwisdom.com as the number to match


Thanks Phil, but I meant what you meant when you said:

Yea! I would like 8.4. Cheesy But I think I might have guessed too high now... We will see. This game is fun. Smiley

Prepare your ass for sub $200 coins!
ymmm, sounds promising, but we need some FUD news

There should be more than enough FUD news in the shitload of new threads started today by newbies with random user names like FW8Dt5, Jd19bW, C6H68g, and ALlYg8. I haven't got round to reading any of them yet because they all look like the work of the same person whose choices of user names are so random that they would make good passwords.

It's one of lambie's new hobbies.

Yup. 24/7/3666
All the world was asleep. Only Baba Yaga sat awake, in her creaky rocking chair, scowling, gnawing on a bone...

BTW, re. overpriced coffee: Bitcoiners think that the cost of a cup of coffee is (the price of coffee grounds) + (usurious profit).
The thought that (price of coffee grounds) = (insignificant, compared to the overheads) never enters the mind.
No wonder you think that trustless blockchain is going to save banks billions quantillions of $.

Yeah, there´s probably staggering overheads, making a cup of coffee is such a complex operation that you probably need extremely high paid staff.

https://finance.yahoo.com/q/is?s=SBUX+Income+Statement&annual

Total revenue 19,162,700,000
Cost of revenue 7,787,500,000
Gross profit 11,375,200

"While the Costa Rica Finca Palmilera beans which went on sale at select locations recently are expensive — they come from a relatively rare cherry of the Gesha tree — the 16-ounce cup should cost just one dollar more than a regular cup of coffee, including the company’s overhead, says James Freeman, owner and CEO of Blue Bottle Coffee. (The price of Starbucks’ regular Grande coffee is $2.20 in New York.) Freeman should know: his chain also charges $7 for a similar cup of Gesha coffee. In fact, an 80% markup is standard in the coffee business on the higher-end brews, he says. Joseph Brodsky, founder and president at Ninety Plus Coffee, which supplies beans to coffee shops in 30 countries, says the new coffee only costs Starbucks an extra $1.30 per cup."

Fortunately for us bitcoin is even more addictive than caffeine. Smiley

Is that when bitcoin wakes up and becomes sentient? It was all a scam to seed the world's first distributed AI. If only we had realized that all along the backdoor to the universe was hidden in the fractional parts of the cube roots of the first 64 primes.

(Those are constants used to initialize SHA-256 for use in its compression function -- nothing up my sleeve numbers.)
194  Economy / Speculation / Re: Bitcoin price cycles on: December 02, 2015, 07:46:31 AM
Agreed, I have this topic watched.  I guess I just feel numb from being in bitcoin for so long, one can only take so many roller coaster rides.  I await good news. hehe
Haha, but I love that feeling. It is cool to not care about huge price fluctuations. Although euphoria of the early days was very pleasurable there is something calming about being ready to expect the unexpected. Then again maybe I am just numb too; as a HODL'r they are just numbers on a screen at the moment...

Well, halving just got pulled back to the 22nd: 2016-07-22 20:56:10 UTC (33 weeks, 2 days, 19 hours).

Is there a thread for betting when the halving will occur? If not, should we make one? Smiley

keystroke = +8.4

Thanks!

Nice security research. Can this attack be made profitable, or is it just DoS?
yes
Aside from someone paying you to DoS. Wink
198  Bitcoin / Legal / Re: Is it illegal for me to sell my Bitcoins? on: November 30, 2015, 04:33:43 PM
Its not illegal as long as you're reporting your taxes.
You can be arrested even if you pay all your taxes. 

I was arrested for selling my Bitcoins using localbitcoins.com

I paid all of my capital gains taxes on all of my trading - that was not the issue.  The legal issue boiled down to one question:  was I operating a business or not.  They claimed it was a business, I claimed it was not.  After being forced to "donate" about $40,000 in cash and $40,000 in Bitcoin to their Federal Asset Forfeiture slush fund we agreed to disagree and they dropped the charges.  Defending me against the federal felony charge [Operating a business without a license, up to five years in prison and a $250,000 fine] did end up costing us almost $300,000 of our retirement funds, our daughter's college fund, our savings, and the equity in our house.

You can read all about it here:

http://www.jmwagner.com/
http://www.burtw.com/

However, if you sell your Bitcoins though an exchange you will not run into this specific issue since there is really no way they can call it a business, go after you, and then grab all the assets they can get their money grubbing hands on.

Read through your story. Respect.
