have anyone test how many token are earned for each contributed vpn node?
Good question. They said 0.7% of all tokens issued will be used for bounties according to this site:
https://mysterium.network/bounty/I don't know exactly, what "tokens issued" means. There are two numbers floating around, according to coinmarketcap:
http://coinmarketcap.com/currencies/mysterium/Circulating supply: 19,429,024 MYST
Total supply: 32,433,365 MYST
If we assume that "tokens issued" means all tokens, that means:
32,433,365/100*0.7 = 227,033.555 MYST
30% of that are allocated to testnet nodes:
227,033.555/100*30 = 68,110.0665 MYST
So, by this calculation, 68,110.0665 MYST are allocated for testnet nodes. That's as far as I got, couldn't find the number of nodes.
