The Chicago Board Options Exchange (Cboe) published the bitcoin derivative contract for investors. The base ticker will be called “XBT” and settlement values of the contract will be in XBTS. This products will have multiple contracts with several expiry cycles and also four serial expirations. As well, Cboe will be offering expanded trading hours for this bitcoin futures. Everything will be cash-settled based on the Gemini auction price for bitcoin in U.S. dollars.

The contract multiplier will be 1 so if a contract is trading at parity with bitcoin it will be worth about $7,900 based on current pricing — The minimum tick for a directional, non-spread trade is 10 points or $10, and a spread trade will have a much smaller tick of 0.01 bitcoin or $0.01.

HashFlare Users to Face Withdrawal Issues

Looks like Bitcoin cloud mining is not super profitable
18 July 2018   130

Users of HashFlare mining pool can't withdraw their funds, while their contracts are threatened with a temporary ban. Even lower restrictions on withdrawal of funds in the amount of 0.03 BTC caused problems for users, but the service raised the threshold to 0.05 BTC and 0.1 ETH . This is reported by Cryptovest.

In addition, financial pyramids are often promoted under the guise of mining contracts for cloud mining. For last few months, there was a big jump in mining difficulty of many cryptocurrencies, so, old contacts had become unprofitable.

As reported, the reason for the locked funds dates back further - at the beginning of June, so much hashing power was flowing into the Bitcoin network that contracts saw all the mined coins go toward their maintenance fee.

Currently, more and more users who have purchased contracts at earlier stages are facing the fact that they can not withdraw their funds. One of them managed to return the money spent through the bank card operator after filing a corresponding complaint.

To anybody that purchased a Hashflare cloud mining contract with a credit card, it might be possible to get a refund with that credit card as one of my followers tipped me. He bought his contracts at the end of 2017.

The hash rate of bitcoin increased from 13 EHash / s at the beginning of the year to more than 40 EHash / s in recent months. The difficulty of mining in the present conditions depends on the circumstances of the specific miner. The cost of bitcoin mining for some of them is $ 4,400, while others spend about $ 5,800. However, in 2018, cloudy mining is called an even more dubious occupation than before, especially when it comes to mining bitcoin.
