When ico will end, what needs to be reached to end it?
If we reach 4000 ETH each next token will be sold for higher price, so there is of dilution for early buyers. Token can be traded with contract immediately and will be soon listed on exchanges.
Reaching minimum target will allow us to continue developing our custom blockchain and after few months crowdsale contract will end and tokens will be converted to final coin. It will be announced early, so each token holder will be able to finally make his mind or sell token back to contract.
