Currently the most of alts are in the red color due to people move their founds in Bitcoin to get as much free coins as it is possible by the 16th November. It is really hard to predict the future of every coin, so I would not hurry to call all of them as scam. The demand is playing the greates role about every coin, the project of a new coin can be good, but if people don't buy it that won't be successful, logically.
