I still believe bitcoin would bounce back to 20k someday and drag alts with it. So I believe in bounty campaign, at least one of this new tokens will survive and we'll have next Facebook or Google.
I also think that when the growth of the market begins we will be surprised about Google and Facebook coins.
If I'm not mistaken, then there was news that Facebook wants to create its own coin.
In any case, if the market recovers, it will become obvious that the cryptocurrency has a bright future.
