New coins cannot simply lead a bull season. Those altcoins that are already on the highest ranks will themselves lead the bull market of the alts. You cannot expect newcomer altcoins to lead the old-timers like ETH, LTC, XRP, and the rest. These coins are definitely the top choices when Bitcoin holders start accumulating altcoins.
I wasn't saying that the new coins can beat things like ETH LTC XRP, top 15 coins will ALWAYS lead. But when it comes to top 500 coins, some of the new guys will outperform the top 100 for sure.
