I think it is more than just weak hands; I think the market is not able to recover because it is exchausted. I think it needs time for it to recover again; so project should be self sustainable now.
Now, during this long bear market, it will be really important that projects be economical with their funds. Only the best projects with a convincing idea and a strong team will survive this bear market.
I am on Icobench every other days, the amount of ICO project coming out these days is drastically reduced, projects are no more economical, they are actually afraid to go on with fundraising
