bit-mining-ssl-error

The Bit Mining service for Litecoin and Bitcoin cloud mining is kind of down yet again, not long since they had another serious issue. Last week the service was apparently been hacked, but it was brought back online and this week the people behind it were trying to fix things and get everything back to normal and about a week now and it still is not fully back to normal. And while they almost did it, now the website is not opening again, giving an error about their SSL certificate not being valid. And this has been going on for more than a day now, though we have notified the support as probably other users did so already and they are apparently looking into the problem. If you disable the certificate validity check in the browser you can apparently login on the website, however this does pose a risk for your security and you should enable the validity check for SSL certificates after that.

The Bit Mining service has been available for a while now, but apparently things are getting out of their control. We just recently started testing the service and more specifically the LTC cloud mining that has been added not so long ago, but our experience so far with the service is more than unsatisfactory. Lots of downtime, problems and things that need more polishing, and along all that the the price drop of the hashrate, making it really not worth to invest into more hashrate. In fact we do plan to sell our 100 KHS of LTC cloud mining hashrate and stop using it and we would recommend you do the same thing if you have hasrate there, and when everything is back to normal we may consider trying the service again. Investing in cloud mining hashrate there for the moment is also not recommended, not until the issues they are having are completely resolved. Issues like that are really killing the users trust in services offering cloud mining hashrate as an alternative to using hardware miners, we’ll keep you updated on how things progress.

pi-crypto-coin

The PI coin is offering an interesting new concept even though it is based on SHA-256 algo. PI coin is the first and only futures crypto and it uses an axiom formula to index the 30-day altcoin futures market. This coin will change the way traders speculate future altcoin prices and trades according to the authors. It had a bumpy start, ad then changed owners, but now things are finally starting to work as they should’ve from the start.

gridseed-5-chip-asic-fanless-power-usage

If you are using the 5-chip Gridseed ASIC devices in Scrypt only mining mode you probably already know that they are using about 8W of power when overclocked. But what about optimizing the power usage even more by removing the noisy fan that might be needed for the 60W power usage in Dual mode or the 50 and something in BTC only mode, but you can go without it in Scrypt only mode. So we did just that, desoldered the fan from the ASIC and ran the device in fanless mode. And surprise, surprise the total power usage without the fan gets down to just about 5-6W overclocked to 850 MHz, but what about cooling without a fan?

gridseed-5-chip-asic-fanless-thermal-image

Running for more than 2 hours already the ASIC in fanless mode mining Scrypt has shown that it can do just fine with passive cooling. The maximum temperature was about 36.6 degrees Celsius at the hottest point with an ambient temperature of about 25 degrees Celsius. Don’t get the wrong impression from the thermal images, these temperatures for passive cooling are more than adequate and essentially the cooling radiator is considered cool, meaning that in Scrypt only mining mode you can do just fine with passive cooling at lower ambient temperatures. If you have multiple units together you might want to have a single big fan with slow rpm just to move a bit of air around them you you can be safe even when the summer heat hits.

A word of warning though, if you remove the fan from the Gridseed 5-chip ASIC devices and for some reason you start a miner for Scrypt that does not stop the BTC mining part or you start the dual mining mode you will have trouble with cooling the device and this can lead to a damage of the ASIC caused by overheating of the chips – most likely the first to blow up would be the voltage regulators. So be careful that you run only in Scrypt mode if going fanless and to use miners that do activate only the Scrypt mining mode and disable the SHA-256 one.
