I think now it's hard to have a coin that can be x500 to x1000 including hot credits like telegram or kodak, as there are now too many coin sizes to break up, just like the bounty program has too many participants now. So everyone's profit will decrease.
LOL. Are you sure? There are plenty of promising ICO right now and most of them have marketable products which was missing on most ICO before. Also, x1000 or x500 is not impossible to achieve IMO, most of the ICO once they hit exchange are at .01 USD and depending on the no. of community it has, it can easily reach 10USD in 1 month.
