Crypto Mining with Google NVIDIA Tesla K80 / P100

Even with the 50% discounted preemptable instances now available in Google cloud, cryptocurrency (BTC, LTC, ETH, XMR, other) mining is simply not profitable.

Despite the shady steemit article “Ethereum Mining with Google Cloud (Nvidia Tesla K80) actually works and is highly profitable”, no,
Mining on these GPUs is simply not a profitable business.

BCN mining on the K80 is about 126 H/s per GPU. ($12/month at the current price/difficulty)

ETH mining on the K80 is about 6.5Mh/s (CUDA Mining)

ETH mining on the K80 is about 7.1Mh/s (OpenGL Mining)

ETH / Sia coin mines roughly 7.1 and 71.8 MH/s (respectively, via Claymore Dual Eth Miner)

BCH – The Green Bitcoin

Bitcoin Cash just became the “Green Version Bitcoin” as Coinbase has made this slightly rotated green Bitcoin symbol the icon for Bitcoin Cash.
Green being for cash, this move makes sense as previously it has been quite difficult to distinguish the two coins, especially with bitcoin.com claiming Bitcoin Cash as the main chain of bitcoin.

 

In my opinion, this new logo is a great step for Bitcoin Cash and reduces much of the confusion from the crappy logo difference between BTC and BCH.

Old Logo for BCH
Current Bitcoin (Core) Logo

 

How To: Convert Coinbase BCH to BTC (Bitcoin Cash to Bitcoin)

Coinbase is posed to allow for BCH withdrawals sometime in late 2017 or early 2018. Given they will only be allowing customers to withdraw their BCH (Bitcoin Cash) many users are interested in having their BCH converted to Bitcoin, Ethereum or Litecoin.

Due to the large amount of Coinbase users planning on liquidating their BCH as soon as it is available, I expect a drop in the BCH value once Coinbase enables withdrawals. The sooner you convert your BCH, the better!

You can get started using one of these conversion links. I will be writting a quick walkthrough below on the process step by step.

BitCoin ETF Request for Comment

The United States SEC has made a request for comment before making a decision on the Winklevoss COIN ETF. Specifically, the SEC needs your help to answer the following questions:

1. The proposed fund, if approved, would be the first exchange-traded product available on U.S. markets to hold a digital asset such as bitcoins, which have neither a physical form (unlike commodities) nor an issuer that is currently registered with any regulatory body (unlike securities, futures, or derivatives), and whose fundamental properties and ownership can, by coordination among a majority of its network processing power, be changed (unlike any of the above). Moreover, as the Exchange acknowledges in its proposal, less than three years ago, the bitcoin exchange then responsible for nearly three-quarters of worldwide bitcoin trading lost a substantial amount of its bitcoin holdings through computer hacking or fraud and failed. What are commenters’ views about the current stability, resilience, fairness, and efficiency of the markets on which bitcoins are traded? What are commenters’ views on whether an asset with the novel and unique properties of a bitcoin is an appropriate underlying asset for a product that will be traded on a national securities exchange? What are commenters’ views on the risk of loss via computer hacking posed by such an asset? What are commenters’ views on whether an ETP based on such an asset would be susceptible to manipulation?

2. According to the Exchange, the Gemini Exchange Spot Price is representative of the accurate price of a bitcoin because of the positive price-discovery attributes of the Gemini Exchange marketplace. What are commenters’ views on the manner in which the Trust proposes to value its holdings?

3. According to the Exchange, the Gemini Exchange is a Digital Asset exchange owned and operated by the Custodian and is an affiliate of the Sponsor. What are commenters’ views regarding whether any potential conflict of interest or other issue might arise due to the relationship between entities such as the Sponsor, the Custodian, and the Gemini Exchange?

4. According to several commenters, there is a need for the Exchange to provide additional information regarding “proof of control” auditing, multisig protocols, and insurance with respect to the bitcoins held in custody on behalf of the Trust, in the interest of adequate security and investor confidence in bitcoin control. What are commenters’ views on these recommendations regarding additional security, control, and insurance measures?

5. A commenter notes that the Gemini Exchange has relatively low liquidity and trading volume in bitcoins and that there is a significant risk that the nominal ETP share price “will be manipulated, by relatively small trades that manipulate the bitcoin price at that exchange.” What are commenters’ views on the concerns expressed by this commenter? What are commenters’ views regarding the susceptibility of the price of the Shares to manipulation, considering that the NAV would be based on the spot price of a single bitcoin exchange? What are commenters’ views generally with respect to the liquidity and transparency of the bitcoin market, and thus the suitability of bitcoins as an underlying asset for an ETP?

6. The Exchange asserts that the widespread availability of information regarding Bitcoin, the Trust, and the Shares, combined with the ability of Authorized Participants to create and redeem Baskets each Business Day, thereby utilizing the arbitrage mechanism, will be sufficient for market participants to value and trade the Shares in a manner that will not lead to significant deviations between intraday Best Bid/Best Ask and the Intraday Indicative Value or between the Best Bid/Best Ask and the NAV. In addition, the Exchange asserts that the numerous options for buying and selling bitcoins will both provide Authorized Participants with many options for hedging their positions and provide market participants generally with potential arbitrage opportunities, further strengthening the arbitrage mechanism as it relates to the Shares. What are commenters’ views regarding these statements? Do commenters’ agree or disagree with the assertion that Authorized Participants and other market makers will be able to make efficient and liquid markets in the Shares at prices generally in line with the NAV? What are commenters’ views on whether the relationship between the Gemini Exchange and the Trust’s Sponsor and Custodian might affect the arbitrage mechanism?
