Really? LoL, ok, maybe ETH is the 2nd generation, IOTA is the 3rd.. really hope that Bitcoin don't take other Big Coins anymore.. But something has to be king, and I thing that is good that BTC rule them all.. because there is no central figure, no miners, no nothing, and that's not true with any other coin..

Something has to give value to all.. and since in ETH Vitalik is king, if ETH goes to top Volume, an if anything that happen to him, it will be caos for all.. unless that the volume change to an equality for the top 10? Maybe by type of Coin, like Security (Monero, Zcash, etc), Platform (ETH, NEO, Lisk, Arc, Tezos, etc), DAG & IOT (IOTA, Byteball, etc), Payment (TenX, Monaco, etc), Media (BAT, AdEx, etc), and maybe some more..
or maybe could be by region, like Asia (NEO, ICON) and rest of the world..
or Capitalist, Communist, and LIbertarianist countries...

Well, this analisis is a little too simplistic and don't take into account that noone has to be in charge, and putting ETH first, there will be a head in there (that is wrong in so many levels, for ETH anyway)..
