They affraid coz you can clone whole operation system, by the way you can do this even without having SSH password;)
I think whole system run from SD card inside miner.
Anybody know what OS running on ebit e9+ miner???
Cloning a system you cant get into to make changes is pretty pointless.
BTW there is no SD card in the ebit, they have an embedded controller very similar to the S9.
It runs linux, just like all the other miners. Most likely based on BusyBox.
