Bitcoin / Legal / Apparently Bank of Thailand clarifies bitcoin exchange is legal in Thailand
|
on: February 15, 2014, 07:30:54 AM

Remember the fuss caused by one Thai exchange last year : https://bitcointalk.org/index.php?topic=264241.0The same exchange now restarts trading. https://bitcoin.co.th/news/ (sorry cant find permanent link to individual posts). Bitcoin Trading Re-Opened January 31, 2014 In a letter to Bitcoin Co. Ltd., Bank of Thailand has stated that, after further consideration, Bitcoin exchange operations do not fall under the scope of Ministry of Finance regulation, unless foreign currencies are also offered for exchange. Considering that Bitcoin Co. Ltd. only offers Bitcoin trades using Thai Baht and operates only within Thailand, we will restart our trading operations. Over the next few weeks we will be re-checking our trading systems; which have been offline for the past months, and hope to be fully operational shortly. Bank of Thailand letter: Download original scan (PDF)I don't read Thai so cant know exactly whats in the letter.... |

It is OK to purchase GH/s from CEX.io !!! Why ? For training  You will learn how real mining for Satoshi is without spending thousands of dollars and waiting on pre-orders. You can have your GH/s instant and you can sell them back too. You can exchange your BTC and NMC right there. You can exercise simple but essential operations like withdraw / add funds / TFA security etc. In the end you will find the answer if mining / trading are really for you. It is OK to purchase lottery tickets!!! Why ? For training You will learn how statistical probability works without spending nights actually reading up on math. You can have your ticket instant and you can sell them to your friends at premium if they have repeating digits. You can exercise simple but essential operations like paying cashier/scratching card/driving to store/physical security(of ticket) etc. In the end you will find the answer if continuing to play lottery is really for you. |

Bitcoin / Mining speculation / Re: Miners Boycot Ghash.io !

You can't compare the price of ghs per ghs of Antminer S1 180 ghs machine to the price you pay to buy a single ghs unit. You got it all wrong. If you want to compare 1 ghs to antminer you have to compare it to the Antminer U1 1.6 ghs USB stick, not to a 180 ghs machine. CEX is not for people that want to buy 200 ghs, unless you are great at trading, it's for people that want to buy a few from them without the hassle of equipment, software, reselling a physical product that its almost worthless in 3 months retarded greedbags who can't do math and don't mind losing BTC in an epic scam, etc. etc. It is also for people to point their miners at ghash..
and if you are smart, you can actually mine for free at cex...the price has not moved much in 3 weeks...that is 3 weeks of free mining as in Zero cost.
Fixed that for you. lol, do you have any evidence that they are a scam? oh you are very smart you probably buy directly from BFL. Or maybe you did your wiz math and just bought one of these? https://bitcointalk.org/index.php?topic=429513.0;allYou are going to get great ROI.LOL Buying pre-ordered hardware is a speculation on when(or even if) they ship... Buying GH/s is a speculation of number of math challenged ppl still around when u wanna sell... ^ This is assuming u are not hobyist. |

Bitcoin / Hardware / Re: CNBC Explains: How to mine bitcoins on your own
|
on: January 24, 2014, 09:17:23 AM

The current number of attempts it takes to find the correct key is around 1,789,546,951.05  So my 180 GH/s antminer can find a 25 BTC block every 0.0099419275 seconds? or rather ~35 blocks an hour? My pool has been very very unlucky all along... time to solo mine... |

Bitcoin / Hardware / Re: [ANN] Introduction to DualMiner USB (could mine both BTC and LTC)
|
on: January 23, 2014, 09:12:03 AM
|
Can these (and other, similar, dual-use devices) mine both BTC and LTC simultaneously? Or is the user (or perhaps mining software) supposed to pick one at a time to mine?
Quote from first page and from the website: Hash Rate: Dual Mode: 40KH/s LTC, 500MH/s BTC, or LTC Mode: 70KH/s LTC, BTC Off Thanks, I missed that on their Web site. But on the first page of this thread, there's no performance info from the OP. I reviewed all posts by the OP, in fact, and he doesn't mention the specs in any of them. Another poster posted the theoretical stats of the chip they're using: BTC mode up to 2.25G/s BTC Hash Rate, with 2.4W/GHash
LTC mode up to 60K/s LTC Hash Rate
Due-Coin mode up to 1.75G/s BTC Hash Rate + 60K/s LTC Hash Rate, or up to 2.25G/s BTC Hash
Rate + 38K LTC Hash Rate So two things jump out at me: First, why is there such a difference between the theoretical stats and the quoted performance, particularly on BTC? And why is the BTC-only mode eliminated? Second, what software would be able to use this gizmo to dual-mine simultaneously? On their site, they say "Customized Windows software with GUI" but they also mention Linux; and their screenshots are of a command-line miner. Depending on how the software is implemented, it may not be able to run on unusual hardware like a Raspberry Pi or Beaglebone. Custom-developed miners are sometimes less efficient than dedicated software like cgminer or bfgminer, so we could be giving up precious hashes. Definitely need more info on this front. We developed a special version cgminer for dualminer. The customization is mainly because cgminer on github doesn't support dual mine mode. The latest version of cgminer even removed scrypt support, :-(. Also we are keeping a eye on bfgminer. We may release a bfgminer for dualminer. Currently only a customized cgminer is developed. As long as we start mass shipping, we will release cgminer that works on Linux. At that time, Beaglebone or PI can be used to control/manage dualminer usb. If you need help with building/testing/troubleshooting with Linux or Pi lemme know... |

Error compiling the qt in linux
make[1]: *** No rule to make target `libleveldb.a'. Stop.
I got past this by chmod +x leveldb/build_detect_platform
The Makefile is missing in leveldb directory, copy it from any of the recent files. but... after that there is obj/init.o: In function `Hash3<char*>':
/xxx/eCoin/src/keccak/hash3.h:16: undefined reference to `crypto_hash(unsigned char*, unsigned char const*, unsigned long long)'
/xxx/eCoin/src/keccak/hash3.h:18: undefined reference to `crypto_hash(unsigned char*, unsigned char const*, unsigned long long)' which i suspect needs nacl library from http://nacl.cr.yp.to/ ... trying it out. Would be nice if OP provides the list of dependencies needed and proper makefiles. |

...Though, — we've also been sleeping in a room with an Avalon, so maybe we've already gone deaf. Sleeping with an avalon, yes you must have gone deaf, when I had mine at home it was one floor up and 2 rooms over and I could still hear it. Tolerance varies per person... have a friend who worked for decades in datacenters... now he finds silence very very uncomfortable... |

did any miner will be usefull for this coin?
Hello, There is both a GPU miner(Modified Reaper) and CPU miner(built in). errrrrr...I think you said in op: Mining: CPU Only so CPU is useless because GPU has more hashrate.. CPU is not useless. CPU still achieves decent hashing on the coin(such as Amazon instances and CPU rigs). GPU is also useful but not to the point of making CPU useless, as is the case with Scrypt. Any hashrate estimates for a specific model of CPU and GPU to form a baseline? |
