some old coins are dead, some still survive, I think new coins and old coins have the same potential to grow, the difference that I see is that new coins don't dare to speculate in big prices. if there is a choice which I have to choose, my choice is still the same, that is, in the old coin, because it is more secure to survive.
New coins are only temporary bubbles to trade in the market. Instead of creating a bunch of new ones, its worth taking up the old ones and developing them because they are already settled, have gone through a lot of obstacles.
