About Heroes Of Crypton
With HoC we are taking play-2-earn block chain technology to a higher level: just imagine playing your favourite super hero meme characters and earning the native token!!!
We have created a play-2-earn gaming platform called Heroes of Crypton which features the block chains favourite meme tokens. It is developed and integrated around MyNFTMarketplace.io. We have designed our platform to stricly run on (Hero Tokens) in game tokens. It gives all our members the chance to purchase HoC NFT%u2019s for staking rewards while playing to earn.
Our Hero in game tokens will also be the only currency MyNFTMarketplace.io accepts, meaning while users mint/buy/sell their NFT Collections all transactions have a 10% Liquidity fee for the Hero tokens. On top, all NFT staking pools will reward daily passive income to our stakers.
