There will always be projects that have no prospects and their original goal was simply to raise funds and, by the way, not the fact that it was for the development of the project, but you still do not need to leave the market ...
If we will not support the market then even the projects can do nothing. All the markets depends on us. We have to hold our money for long term which we invested in Bitcoin and altcoins. We have to promote the projects among those who want to invest money and have to tell them to invest in BTC and other high potential altcoins.
