Hi.
Is it mandatory to use docker? No other way?
And how many coins does a running node get on average? And will test coins moved to the main network?
So, yes, mandatory to use Docker, no other way at this stage.
In regards of the average coins, it really depends on a lot of parameters. Best is to try and check by yourself.
Test-GTU won’t be moved to Mainnet no. But early testers will get a significant advantage at launch if you follow my thoughts.
