Is there a chance for invest some waves again?
Yes, another 16 hours left to do that. Don't forget you'll also get a 5% bonus on top if you deposit Waves!
after ico ended then when distribution incent?
Most likely mid of December.
Nice to see that if Incent almost Finished their ICO about 18 hours left and they are collected much BTC and waves too..one thing Im very happy if they are get listed on bittrex as soon as possible after this ICO

They will if Incent pay the fee to added at Bittrex, but is quite hard added in Poloniex, but Poloniex or Bittrex incent just need to always develop their project so incent token will gain value
It's not that easy nowadays
