They can still conduct IEO in another exchange,
They will not hold IEO again.
they are about listing on bitrue. although the exchange is not well versatile as top exchanges like hobit, binance and co. it will be preposterous to see hacken another new emerging project go down so easily. the project looks young and has a lot of possibilities.
Bitrue is not very popular, but it's a good exchange for starters. In the future Hacken will definitely be able to enter a bigger exchange.
ICO is still a possibility if they are unable to find another exchange for conducting IEO.
They had held an ICO a few years ago.
