Hello fellow Bitcoin hackers,

looking at ticket prices of upcoming conferences this year I got a little bit frustrated:

Bitcoin in the Beltway Washington: €294
Inside Bitcoins Hong Kong: €294
WIRED Money London: €1248
Bitcoin Finance 2014 Dublin: €599
Inside Bitcoins Conference & Expo Melbourne: €276
CoinSummit London: €677
Annual North American Bitcoin Conference Chicago: €202
Coin Congress San Francisco: €331
Cryptocon Sydney: €913
Cryptocon Singapore: €883
Inside Bitcoins Tel Aviv: €368
Bitcoin and Cryptocurrencies St. Petersburg: €37 (or donation)
Cryptolina Bitcoin Conference Raleigh: €202
Camp Bitcoin Black Rock City: ? (probably donation)
World Bitcoin Forum Bonn: €300
Bitcoinference Summer 2014 Amsterdam: ?
Bitcoin Central & Eastern European Conference Ljubljana: €300
Inside Bitcoins London: €495
Bitcoin Conference Kiev: €75
Bitcoin World at Money2020 Las Vegas: €2171 (yeah, baby!)
Dubai Bitcoin Conference: ?

With the notable exception of the St. Petersberg conference and the Burning Man camp the events are obviously not targeted at free software developers or mainstream users. So I propose to organise an event that is accessible to a broader audience, similar to the open source conference FOSDEM (https://fosdem.org/):

• Free entrance / donation
• Location at non-profit or academic venue
• Possibility to volunteer
• Free booths for free/libre open source projects
• Lightning talks
• Hackathon/dev rooms
• Workshops for beginners
• Possibility to trade/withdraw/spend cryptocurrency
• Family-friendly
• Colourful start-up fair
• Friendly security staff (if any)

Let's make cryptocurrency conferences less about suits, but more about community and fun (hello shibes)! Ideas, comments, pointers to similar proposals welcome.

Cheers, Meinhard.

Edit: Added Coin Congress

hi jeff,


i think you will find everything you need to know (and much more!) in miaviator's complete guide: https://bitcointalk.org/index.php?topic=494625.0

@miaviator excellent guide by the way! respect.

i didn't follow up on mining with gridseed by the way, because a few other things distracted me recently. my single gc3355 is now sitting in a box doing nothing. :-/

hallo liebe cloud-mining interessierte,

bei meiner recherche zu deutschen cloud-mining-anbietern bin ich auf http://btc-cloud.de/ gestossen. routinemaessig habe ich kurz nach dem namen im impressum gesucht: "norman poetzsch, pirna". und boom, es gab gleich dutzende treffer, die ihn mit diversen betrugsfaellen in verbindung bringen, z.b. http://paid4magazin.de/index.php/facebookpromotion-de-alles-gold-was-glaenzt/

..der typ hat echt nerven, es jetzt unter gleichem namen mit bitcoin-mining-vertraegen zu probieren.

also, aufgepasst beim vertragsabschluss!

hat jemand erfahrungen mit dem anbieter?

dear cloud mining enthusiasts,

while researching german cloud mining services i came across http://btc-cloud.de/. routinely i checked the name in the impress with a quick search: "norman poetzsch, pirna". and boom, i got dozens of hits linking him to various fraudulent activities straight away, for example http://paid4magazin.de/index.php/facebookpromotion-de-alles-gold-was-glaenzt/ (a german special interest blog about paid-to-surf offers)

..this guy really has guts to now try his luck with bitcoin mining contracts under the same name.

so, watch out when ordering contracts!

any experiences with this service?

Hi Scrypt miners,

I was lucky enough to get one of the first Scrypt ASICs produced by Chinese GridSeed during my stay in South Korea last month. Cheers to Dis Btopia of xbitcoinx.com! I just hooked up one unit containing 5 chips to my Ubuntu box via USB port and here is what I did to get it running. Mind you, these instructions are for mining Scrypt, not SHA256 or dual mode, which the ASIC can also do. Most of the information I pieced together from this post in Chinese: http://cybtc.com/article-468-1.html

Download GridSeed's modified cpuminer and unpack zip file:

..or download via git:

Install automake:

You might need to install other compiling tools. I didn't need to, because I compiled other things before.

Compile:

Connect and power up ASIC.

Find correct USB device:

..or watch syslog while plugging in ASIC:

Start mining (replace "ttyUSB0" with device found above and add your pool data):

You should now see lots of output with yellow "LTC" lines. If you see red lines, that's bad. Anyway, post here if you run into troubles.

I am not quite sure what the green and red LEDs are about. As far as I can tell there is no English documentation about that anywhere. I assume green (which is on as soon as power and USB are connected) indicates a certain ready state and red (which flashes sometimes) means hardware errors.

I am getting a lot of "Invalid nonce" errors in the cpuminer output along with red LED flashing. Probably because by mistake I got a 12V/0.5A power supply instead of 12V/5A and chips run low on power. So I can't tell you much about hash rates etc. right now. I'll get another power supply next week, so stay tuned.

great idea, i'm in! all your base are belong to bitcoin..

How is this Reuters news? The (silly) physical bitcoin photo is attributed to "Reuters / Jim Urquhart" (http://straylighteffect.com/category/about-jim-urquhart/), but the article is RT. There is no mentioning of a bitcoin "ban" in Russia on reuters.com. Just this piece of fine journalism that claims bitcoin is "banned" in Indonesia: http://uk.reuters.com/article/2014/02/06/uk-indonesia-bitcoin-idUKBREA150HV20140206

I'd say some people at RT (and everywhere else) made a few bitcoin through other people's panic sales today. :-P

update:

through the bitcoin korea facebook group (https://www.facebook.com/groups/359243667542297/) my girlfriend found this: https://www.ddanzi.com/?mid=bunkerNotice&document_srl=1890381

from what i understand via google translate it is a two part event. a keynote event on 16 jan 7:30pm and a more informal meet-up with roger ver on 17 jan 7:30pm. apparently on the second day english translation is provided.

i *think* the location is a place called "bunker1" (http://bunker1.ddanzi.com/bunkerAbout). gps coordinates: https://maps.google.com/maps?q=37.5782483,127.0047312

participation is free, with no visible registration process. doors close when venue is full.

gee, this is really not very accessible for the non-korean speaker..

see you there!

annyeong seoul,

excuse my english post, but i don't speak korean (yet). i work on a few cryptocoin projects and i am staying in korea for a couple of weeks. so i am trying to get in touch with "bitcoiners" while i am here. i already visited korbit, zecca cafe and "that bakery in incheon". all meetings were delightful and i hope to meet some more people before i leave on 2 february.

several people told me about a bitcoin meeting on 17 january, but i can't seem to find any (english) information about it. does anyone know details or can point me to a website?

cheers, meinhard.

it just says "Due to a mass of trolling" in https://bitcointalk.org/index.php?topic=15958.0 - whatever that means. i assume that some people signed up with several accounts in a short period of time and flooded threads with non-sense. or does anyone know what else they meant by "trolling"?

hi there,

i bought 19.6 gh for 1 btc on cex.io 2 days ago. including what was mined in roughly 48 hours (0.012 btc) my cex.io position is now worth 0.9 btc, so i lost 0.1 btc due to the price drop of gh in the last days.

with new much faster mining technology flooding the market all the time the gh price will continue to go down i'd say. even if you reinvest all your mining earnings in gh you probably will not make a profit, unless gh price goes up or stays stable while you mine.

the cex.io price graph only goes back 30 days unfortunately, so i don't know how the gh price developed over the last months. maybe it actually went up at some point due to shortages in hardware delivery?

but hey, if you want to try it out anyway sign up via https://cex.io/r/0/meinhard/0/ and help me to cut my losses with some referral income.

what exactly do you mean by "charity"? aren't there enough coins out there that can be used for charity? what will make your coin different? just wondering..

..with these settings i only got around 660 kh/s with my XFX R9 280X TDFD.

this works best for me (~740 kh/s):


i am running cgminer-3.7.2-x86_64 on xubuntu 13.10 with catalyst 13.101. does anyone get better results for the same card on linux?

cheers
