The number of good projects is decreasing since 2017. I remember in 2017 there was a lot of promising projects, and you had the possibility to earn good profit by investing in any ICO project almost. Now the situation is harder, and you need to make a careful and long research before investing your money or time in any ICO project.
Of course, 2017 is a very profitable year for all of us who are in cryptocurrency, all ICO projects can be very profitable in that year because in that year bullrun occurred, coins experienced a very high price increase and if we look at the current situation indeed very much different, we certainly want it to be repeated, so to me because there is something that makes me feel sorry for not selling all the coins that I have that year.
