The total amount of crypto currency (PCX) issued by ChainX will be 21 million, which is halved every two years.
20% of the first two years circulation is owned by the founding team for ongoing development funding. After two years, the chain will be fully owned by the community, so the founding team will only own 10% of the total.
The assets (BTC, ETH, etc.) in ChainX that user deposit in through inter-chain bridge will automatically convert to PCX value according to daily average price,then ChainX will issue new PCX according to the total market value of users'assets.
The PCX that user mined can be used to pay for miner's fee and validator's deposit, vote for validators, and act as intermediate currency for trading some minority assets.
Polkadot's investors can map the DOTs on Ethereum into ChainX, and participate in inter-chain asset mining with BTC depositors. ChainX will preheat the Polkadot ecology in advance.
