In the past years, I witnessed some events where some altcoins don't rise again after they suffered a damaging blow when their market sink to the bottom. I guess their developers lose hope when they saw their project has lost its popularity and honor to the investors. when that happened, they just quickly give up and switch to another project to develop which give them more opportunities than the old one. Filecoin should be carefully studied give updates to their investors so that they can expect their support even though the market is not looking good right now.
