Should i add another s7 or save up for a s9?
Is the S9 are the one from Bitmain with few backdoor ??
I so, I'll never buy one !
After all the kerfuffle about that (never activared) code it has been entirely removed by Bitmain. Introduced in the 1st s7's it was for folks to have remote-access to their miners via the Cloud but the service was never implemented.
