Topic: Insider's story on Asicminer's debacle(2013-2015, in Chinese) (Read 456 times)

Internal and external, keep on fighting, defeated, unusually cold this winter, the most unlikely of grilled foot of the cat lost contact.

4. grilled cat foot I must say a few words.

I was an early investor in the stock cat roast, grilled cat is the first to use the mining machine mining beneficiaries. I roast cat technical control, since April 2013, the company and the industry to control mistakes again and again, mistakes continued to the front foot.

2013 Spring Festival, grilled cat 12.8G mining machine to come out, chips, production, improved model has been no mass production.

In 2013, the roast cat holds a lot of wealth, huge amounts of money to establish a liquid-cooled mine, although interesting but certainly lose money. Some people argue that within the team into the 28-nanometer, the board did not pass.

2013 8--9 months, the currency price of around 1300, when the cat roast sold 20,000 coins, ready to develop 40 nm. November 55 nanometer chip BM1380 bit continent advent swept the global market, there is a small episode, we BM1380 the wafer (length and record the same, but the seal, the outside can not see is the wafer) in the courier warehouse stolen gone, the thief did not know what, along with tea together next away, and later found in the dumpster, sawed, and can not use, we lose tens of millions.

Early 2014, the cat roast 40 nanometer tapeout, we have developed 28-nanometer tapeout until early April. Avalon month later than we taped. In late April, the cat roast samples arrived, very good argument, grilled cat has not been resolved to the mining machine from the chip manufacturing process, began to sell chips, then there were minor strong mining machine, dragonflies t-east mining machine, mining machine garden etc. , but until the end of June, the East t in the industry production of the first batch of baked chip mining machine cat, other generation business are still struggling to develop and test. In mid-July, we started to sell large S3, the previously mentioned production of 20 million units. This generation of generation of business losses roast cat and the cat roast directly related to the development process has been constantly jump pit. Chip package in the tank, and the temperature another job Chips. Roast cat generation chip really fight, and under a massive wafer, but the delay is not developed it. Later these chips made of roasted and grilled cat cat pipe prism, small miners forum, but who bought a batch of roast cat mining machine, with miners words, it is the old worry about. Prism nominal 1.4T, 1.1T can go pretty good, but power consumption is much higher than the standard to be, and failure continued. Later that every time we publish mining machine, friends have asked me, can not go to so much, I say never vacuity bit continent.
Here revisit the story, 28 nm is rather special, it is all just march. There is a small parameter, we ignore, leading to higher chip power consumption, Avalon day before tapeout discovered the problem, urgent revision, the change will take more than a month, mining areas, time is actually money. iphone6 ​​many chips are 28nm, TSMC also, we have to grab their capacity.

July 2014, the mainland get bit sampling parameters slightly lower than expected, but still very good arguments. Then we did a version, 28 nanometer part of a custom library, Sept. cast film, which is BM1384, the main models for the S5. Roast cat into the development of the next generation of course, but we all know he has twenty thousand Dollars But it is his personal money, of course, risk can not be used, it should be financing or borrow (pure speculation), but not directly to the cat roast lot cast film, but made a MPW. Silicon chip to two months, he made a MPW (that is to test the chip can not, the number of chips small, but mpw be very cheap) is tantamount to a waste of two months.

In January 2015, he got the cat roast chip, this chip is really good ah, 1T also more than 300 watts, but this time we S5 volume production, and we have completed the construction of large-scale mine in Sichuan. But Bitcoin has been diving, grilled cat models or 40 nanometers, struggling to put the chip into a mining machine inventory and cooperation of third-party mines reportedly cut away the cat roast operator force, as mines and roasted cats scores, here I do not know do not say, anyway, he did not count the cat roast forces, and these forces by the operator Xiaoqiang AMhash and calculate the force it has been sold, the cat roast force to pay for these benefits to be considered Users of these two forces cloud platform operators, their chips, although very good, but money seems to cast film scene is not good. Internal and external, keep on fighting, defeated, unusually cold this winter, the most unlikely of grilled foot of the cat lost contact.

Let me say a bit continent, although once the price we S5 1700, but there are still some profits, and we have the first two generations of capital reserves, we are moving steadily, at every step, we do not sell hosting to their own mining machine inside the venue. March 2015, PACMIC V1 launch, and users to share our mining revenue, of course, we have to return the money. From the beginning to now, mining difficulty average increase of 1% each, Bitcoin mining is one of the few in the history of the golden age. bitbank pine flower show, haobtc Wu Gang, both at the beginning of the procurement us a lot S5, today, S5 price remained at around 2600. Bit mainland listing plan has already started, is expected to log on Nasdaq two years.

4.烤猫跑路我顺带说几句。

我是烤猫股票早期投资者，也是最早使用烤猫矿机挖矿的受益者。烤猫本人是技术控，自从2013年4月，对公司和行业的把控连连出现失误，失误一直持续到跑路前。

2013年春节，烤猫12.8G矿机就问世，芯片，生产，改进机型却一直没有大量生产。

2013年中，烤猫公司持有大量财富，巨资建立了液冷矿场，尽管有意义但是肯定是亏钱的。团队内部有人力主进军28纳米，董事会没通过。

2013年8-9月份，币价1300左右的时候，烤猫卖掉了2万币，准备研发40纳米。11月份比特大陆的55纳米芯片BM1380问世，横扫全球市场，这里有个小插曲，我们BM1380的wafer（长的和唱片一样，但是密封的，外面看不出是wafer）在快递的仓库里被偷走了，小偷不知何物，连同旁边的茶叶一起拿走了，后来在垃圾站发现了，被锯开了，没法用了，我们损失了几千万。

2014年初，烤猫40纳米投片，我们28纳米一直研发到4月初才投片。阿瓦隆比我们晚一个多月投片。4月底，烤猫样片到手，参数很不错，烤猫一直没解决从芯片到矿机的生产制造过程，于是开始卖芯片，当时出现小强矿机，东叔的蜻蜓矿机，花园矿机等等，但是直到6月底，东叔在业内量产了第一批烤猫芯片矿机，其他代工商还在苦苦研发测试。7月中旬，我们S3又开始大卖了，前文提到生产了20万台。这一代烤猫的代工商的亏损和烤猫也有直接关系，研发过程中一直跳坑不断。芯片封装被坑了，温度高就炸片。烤猫这一代的芯片真是拼了，下了海量的wafer，但是迟迟研发不出来。后来这批芯片做成了烤猫管子和烤猫棱镜，论坛里矿工不多，但是谁买了这批烤猫矿机，用矿工们的话来说，那就老操心了。棱镜标称1.4T，能跑到1.1T就不错了，而且功耗也比标准的要高很多，而且故障不断。后来以至于我们每次发布矿机，网友都问我，能不能跑到那么多，我说比特大陆从不虚标。
这里再讲个故事，28纳米比较特殊，大家都是刚进军。有个小参数，我们忽略了，导致芯片功耗偏高，阿瓦隆在投片的前一天发现了这个问题，紧急修改，这一改就花了一个多月，挖矿领域，时间其实也是金钱。iphone6的很多芯片都是28纳米的，也在台积电，我们还要和他们抢产能。

2014年7月，比特大陆拿到样片，参数略低于预期，但参数还是很不错。紧接着我们又做了一版，28纳米部分定制库，9月份投片，这就是BM1384，主力机型为S5.烤猫当然也进入下一代的研发了，而且大家都知道他有两万币，不过这是他个人的币，当然不能拿来冒险了，应该是融资或者借钱了（纯猜测），但是，烤猫没有直接去大量投片，而是做了一个MPW。芯片流片要两个月，他做了个MPW（就是测试一下芯片能用不，芯片数量很少，但是mpw要很便宜）等于是浪费了2个月时间。

2015年1月，烤猫拿到了芯片，这颗芯片真是不错啊，1T也就300多瓦，但是这时候我们S5已经量产了，而且我们在四川的大型矿场已经建设完成。但是比特币已经跳水了，烤猫的机型还是40纳米，苦苦把库存的芯片变成矿机，然后合作第三方矿场据说切走了烤猫的算力，至于矿场和烤猫的恩怨，这里我不太清楚就不说了，反正了烤猫自己没算力了，而这些算力通过了小强的AMhash 和 算力吧已经卖了，烤猫要支付这批算力的收益给这两个云算力平台的用户，自己的芯片虽然很好，但是投片似乎钱景也不好。内忧外患，屡败屡战，屡战屡败，这个冬天异常寒冷，最不可能跑路的烤猫失联了。

再说说比特大陆，我们S5虽然一度售价1700，但是仍有一些利润，而且我们有前两代的资金储备，我们稳扎稳打，步步为营，我们把没有卖掉的矿机托管到自己的场地里面。2015年3月，PACMIC V1推出，和用户分享我们的挖矿收益，当然我们也回笼了资金。从年初到现在，挖矿难度平均每次增长1%，是比特币挖矿史上为数不多的黄金时代。bitbank的花松秀，haobtc的吴刚，都在年初采购了我们大量S5，时至今日，S5的售价仍然在2600左右。比特大陆已经开始启动上市计划，预计2年内登录纳斯达克。
