i wouldnt suggest ico's at all due to the reason that most of them are purely frauds . they will only collect the money from the public and will run away pretty easy .
@op not bad for a first timer . congrats because you manage to earn on mining , i really thought mining is only a waste of time but you prove us wrong . anyway , if you feel that mining can give you a good stable income , then you can just continue doing it . dont ever risk your profit from unsure investments like ico's or even on cryptos .
I guess for everyone who saves money in cryptocurrency in 2018 will meet the same thing, be it invest in ICO or in the coin/token that has been listed on the exchange. Take a look at the ICO project in 2017, very promising and only a little of the project is a scam. However, this year with a continuously to decline in prices caused by a number of things from the government or a company, it has an impact on a project, not a few of them who failed to reach the target then ended up in a scam. I just think if the cryptocurrency market is still the same in 2017, the ICO scam will not be there.
