I am not surprised for now when there are many unclear projects and many disadvantages to investors, for 2018 there have indeed been many unclear projects, but for 2017 there are more good projects than those that are not clear
In terms of looking at several projects it is necessary to have a comparison, but we also have to look at the condition of the crypto market every year, as in 2017 where the crypto market has a positive response from investors, so that it is used by scammers in the following year, namely in 2018 and continues to 2019 until now.
