Hello there, I’m a programmer. I’d like to enjoy this fantastic project.
Yesterday night I successful set up two cardano node follow Installing the node from source — cardano-node Documentation 1.0.0 documentation
They are ok, but now i don’t know what’s the best configuration.
I’d like to earn some coin too. Do i need to stake some coins on a cold machine? Or can I setup some server on the network and earn without stake? There’s a lot of things to do and I’m a little confused. 
Any help or visions will be appreciated
Some one could help me?
thank you
Hello,
Welcome aboard!
There are two ways an ada holder can earn rewards: by delegating their stake to a stake pool run by someone else, or running their own stake pool. The amount of stake delegated to a given stake pool is the primary way the Ouroboros protocol chooses who should add the next block to the blockchain, and receive a monetary reward for doing so.
The more stake is delegated to a stake pool (up to a certain point), the more likely it is to make the next block – and the rewards are shared between everyone who delegated their stake to that stake pool.
