It is hard to really determine which coins are scams. Not unless if many will be complaining on them. It really doesn't matter for me what coins are there because anybody could just do scams as a way to get easy money. The best way to invest would be to enter exchanges of known profiles and is trusted by many. Don't get too much attracted by ICOs. Some are good but failed in the end due to market crisis as a result they are branded as scams.
