Thank you for your advice, but I think it is not good time to take part in ICOs, most of the ICOs have not enough value, but so much risky.
There is a concept in business which states, "the higher the risk, the higher the return." Indeed, ICOs are extremely risky to invest in, but choose the right one and you can turn a few hundred dollars to millions! You don't need to look far, just look at bitcoins. BTC started like $0.000001 or even a lot more zeroes. That translates to millions of dollars if you bought some back when it started.
Exactly! And the good thing is that if you are even able to identify to some good extent the ICO that is not worth it, based on the team, the availability of product and how relevant that product can be or useful to the world entirely, then you should at least know you are taking some calculated risk with the possibility of a high return which even makes ICOs awesome to be a part of. You can only be exposed to a huge risk if you just invest blindly.
