What goes up must come down phrase doesn't apply to ranks in altcoins. If it goes down, It digs the ground and bury itself.
3. History have proven that many altcoins will be replaced by new ones and that's where huge investors will be making most of their gains in next bull market.
This I know for sure its true. Look at NEM and DASH that I have been holding for years. They are not even on top 50. They used to be the top coins, whats worse is their price didn't also made it.
