I think its a good strategic decision to extend the ICO in order to accommodate more prospective investors to participate in it given that the crypto market is not quite good right now.
then they extended the private sell until 9 april and it was certainly a strategic move, perhaps dictated by the low value/volumes of the market and maybe the low investments received so far?...
If the market changes and starts to raise again the difference between extending the ICO and not could be huge.
