2x Antminer 4,0Gh Sha256 24/7 ON and stable

Important :

Please set difficulty max 32. If you set diff like 16.4k or 32.8k, 99% of time result 0 hashrate. That means you are losing rent time.

Please make sure you add two or more different pools, to prevent downtime

Difficulty :
Please adjust your worker to minimum difficulty (I recommend set difficulty to 8). My rig will produce better performance.
Setting the difficulty minimum high and will take much longer to process successful shares and as result a low or even 0k hashrate.

Downtime :
If my internet, power, or rig go’s down I will extend on to your rental time by duplicate the downtime (minimum 1h bonus)
Please feel free to leave a comment if you have any issues.

Some info :
