Dear Users,

Please be informed that despite considerable Bitcoin price growth, it is still not enough for profitable Bitcoin mining, taking into account current difficulty and maintenance cost.

Take a look at the following calculations:

There’s an average number of more or less 3,600 BTC gained from mining each day. The hashrate is currently about 480,000,000 GH/s. Thus, the expected Bitcoins/month with 1 GHS can be calculated this way:

1 GHS/overall network hashrate * Bitcoins generated per day * 31 day

1GHS / 480*10^6 GHS * 3600 BTC per day * 31day = 0.0002325 BTC ~ $ 0.09 per month (at 400 USD/BTC rate)

Meanwhile, 1 GHS maintenance per month is $0.105/month. Thus, mining is not profitable at the moment. Moreover, the estimated next difficulty increase is in about 1 week. Provided the Bitcoin price won’t change much, there is no positive forecast for profitable mining in the nearest time.

Note that the calculation is very approximate and can be negatively changed by pool luck. Moreover, not only the price has to go up, but also flatten out at a certain level, for mining to be truly profitable.

At the moment, owners of cloud-based GHS on CEX.IO are free to choose 2 options:

– let CEX.IO decide the mining behaviour (where we will be monitoring the mining difficulty and Bitcoin price and switch your GHS cloud mining power depending on profitability);
– control cloud mining at their own risk (enable on their CEX.IO Profile > GHash.io tab (https://cex.io/trade/profile#miner) > Turn off Let CEX.IO Decide > Turn on cloud mining).

Please pay attention that you fully undertake the risks when choosing the second option.

Since ride-sharing platform Uber has denied rumors saying that it is accepting bitcoin transactions and clarified that this feature is not yet in the pipeline, Bitcoin Builder sought to create a workaround by offering users access to its Uber business account to make bitcoin payments. However, Uber decided to suspend this particular account this week.

Bitcoin Builder is still appealing to Uber to reinstate the account and, according to a message shared on Reddit, the company will reexamine the suspension.

Uber Payments Thru Bitcoin Builder
As it turns out, Bitcoin Builder is facilitating these bitcoin transactions by receiving the funds and then granting customers access to their business account. The user is required to enter his/her email then deposit a minimum of $10 into the Bitcoin Builder wallet. From there, the user’s personal Uber account must be linked to Bitcoin Builder’s business account from which the bitcoin payment option can be used.

Some questioned that this might be in violation of Uber’s business account policies, as this is offered to companies that are seeking to reduce transportation costs or allowances to their employees. Others say that Uber is against the company requiring a minimum deposit and maintaining balance, turning the app into a prepaid service.

Uber and Bitcoin Builder haven’t issued any official statements as of this writing.

According to the message Bitcoin Builder shared, customers who have made deposits can be able to get a full refund of their balance anytime. However, the company appealed to users to wait for a few more days in case they are able to reach an agreement with Uber itself.

So far, Uber hasn’t shared any updates on whether or not they’re looking to accept bitcoin payments anytime soon, although many are hopeful that this feature can be added due to popular demand. For now, drivers are being creative with asking for tips or donations in bitcoin by posting their wallet QR code inside their vehicle or giving away business cards with the code.
