If no more new coins were made for a year then things would sort themselves out. Some would die others would do well. But with more coming out almost every day, it is having a negative effect on all of them, people don't know what to think. One new coin is basically the same as another. They are not distinguishing themselves.
Thats when you learn to spot those that are somewhat decent.
Ive said that you do almost need to other coins with low dif or have been out a bit with low difficulty... because mining say... LTC is impossible for a normal user. I know many think of it as an investment... but those are not the people you dont need to target... its those that are not sure. Those that are not sure dont have more than 300kh and if they cant mine they aint gonna stick with the cryptos.
