POWH - PoWH3D: Cryptocurrency in Three Dimensions
Proof of Weak Hands 3D (PoWH3D) is the world's first three-dimensional crypto currency that generates you ETH just by holding the tokens!
https://powh.io/?masternode=0x36ed2d75a82e180e0871456b15c239b73b4ee9f4 - may as well use my masternode link here, seeing as it's unused! buy P3D tokens and collect dividends when anyone else buys OR sells theirs. Proove how strong your hands are and watch the divs pour in! Buy 5 P3D tokens to get your own masternode so you can earn 3% of however much is bought using your MN. Its a smart contract that can't be taken off the blockchain, so in theory these divs could last forever!
