All is explained in the Whitepaper, also some information is up the top of the thread about Bounties.

"There will be a Twitter Campaign along with incentive for Youtube Channel Owners who do reviews, mentions or shout outs towards EarnzCoin [ERZ]"

8K coins are needed do run a Masternode, the Minimum/Maximum purchase during the Pre-Purchase Phase is in 8000 coin bunches, meaning that whilst getting into ERZ you also get a bonus initial incentive to turn on and run your own MN to start earning extra EarnzCoin instead of grinding with staking or mining.

There will be 5x Rounds for the Pre-Purchase Phase, 10c, 20c, 30c, 40c & 50c entry points, each has a total limit of 800k for sale equating to 100 Masternodes on offer for each Phase totaling 500 potential MN's that will be active come a full sell-out.
