There is no guarantee that there will be a market reversal for altcoins.
Time and again alts blew my expectations into the weeds. I kept thinking 'how can this utter junk keep going?' and then it doubled again.
The only things in terms of this market we can depend on are greed and stupidity in the face of it. That means at some point an alt explosion is inevitable. I guess most people care about which alts and that's the unpredictable element.
The pumps may be less sustained and less generalised. It's one of the things I'm most curious about. I don't think it'll resemble 2017.
