Because it is a bear market, it is very difficult for anyone to make money by issuing coins. So many investments are losses, so everyone thinks that they are frauds, but not necessarily. Last year was a bull market. Investment would not be considered as such, but many of them are also frauds.
Maybe its true. Bullish and bearish is depending the demand of investors in the market.
Bullish means much demand, demand to exist coin and also new ico project and it makes many new project just success and now many fail project because no demand and it make the people said so.
