Yes i agree, so many projects are extending their period right now. But i think its very normally, due to the developer and the team of their project are afraid to publish their token hastily. They confused with this situation, the market is very unstable and all the prices of altcoins were falling down / decrease. So the team are avoid dump and this bad situation. And also the other reason their extend the project due to they have not reached yet their fund and still need more investors.
