* Team JUST presents..* Trevon James Presents....

* *
* ====================================*
* -> What?
* The original autonomous pyramid, improved:
* [x] More stable than ever, having withstood severe testnet abuse and attack attempts from our community!.
* [x] Audited, tested, and approved by known community security specialists such as tocsick and Arc.
* [X] New functionality; you can now perform partial sell orders. If you succumb to weak hands, you don't have to dump all of your bags!
* [x] New functionality; you can now transfer tokens between wallets. Trading is now possible from within the contract!
* [x] New Feature: PoS Masternodes! The first implementation of Ethereum Staking in the world! Vitalik is mad.
* [x] Masternodes: Holding 100 PoWH3D Tokens allow you to generate a Masternode link, Masternode links are used as unique entry points to the contract!
* [x] Masternodes: All players who enter the contract through your Masternode have 30% of their 10% dividends fee rerouted from the master-node, to the node-master!
*
* -> What about the last projects?
* Every programming member of the old dev team has been fired and/or killed by 232.
* The new dev team consists of seasoned, professional developers and has been audited by veteran solidity experts.
* Additionally, two independent testnet iterations have been used by hundreds of people; not a single point of failure was found.
* *
* -> Who worked on this project?*
* - PonziBot (math/memes/main site/master)*
* - Mantso (lead solidity dev/lead web3 dev)* Proof of Trevon James
* - swagg (concept design/feedback/management)* Don't Talk To Me Unless It's About Intangible Coins.
* - Anonymous#1 (main site/web3/test cases)*
* - Anonymous#2 (math formulae/whitepaper)* -> What?
* Incorporated the strong points of different POW{x}, best config:
* [✓] 20% dividends for token purchase, shared among all token holders.
* [✓] 10% dividends for token transfer, shared among all token holders.
* [✓] 25% dividends for token selling.
* [✓] 7% dividends is given to referrer.
* [✓] 50 tokens to activate Masternodes.
**
* -> Who has audited & approved the projected:
* - Arc
* - tocisck
* - sumpunk
