Well done - good article! I agree with you in most parts. At one point there will be a combing and only strong ideas/concepts with strong dev.team will suxeed. Many of the 725 coins out there are ridicolously uncreative, with no innovation some, as you mentioned, mostly hype & promotion. I wont cry if only 50/725 are left in 20 years aslong as survivers include my long term investment mix BTC,ETH,LTC,LSK,GNT.KMD with investment volume flattening from left to right . . . I can live well without hill-ary coin or INSANE COIN even if the prize expldes right now for no reason!
