Don't forget that 1BTC = 40 000 BOSCOIN during the ICO in May 2017.
So according to the exchange rate of BTC, 1BOS = 0.45$
If it's under this price on the exchange (not IOU price), it mean that we lost money from the ICO.
According to the new project and the long time to reach an exchange, Hope at least from x2 until x5, so probably between 0.90$ and 2.25$
Under, It would be probably a waste of time to put money 7/8 months ago on this ICO.
