In order to earn coins it is enough for me to keep them in my wallet? How many coins do I need to keep in my wallet to earn money?
You need at least 10,000 coins to earn rewards. They are blocked and you run 1 masternode
and what dollar amount is needed for that? do you have such information? and whether there are any requirements to the server ? I would like to get more technical information.
here is a detailed video on setting up the server step by step. it's pretty easy.
