hi everyone, is it possible that the rig with 5 rx580 crashes the internet line? Hacker?
This is possible but unlikely. It is more convenient for a hacker to make sure that some of the shares go to his wallet. And from the fact that your mining farm crashes, no one will get a profit.
Install the latest version of Hive Os and set up mining.
You don't need a high internet speed for mining, a few megabits per second is enough (at least)
