In IC, you can invest regardless of the state of the market, the essence lies more in the project itself. Study the project, consider possible perspectives and of course its very essence in the description. Look for all possible information before making a decision. The success of your investment will depend on the success of your choice.
I think that today all activity in the cryptocurrency space carries a very high risk and even investments in ico companies today can bring negative results. The fact is that if we compare today's market with the market of 2016, today it is not clear what is happening.
Investing in ICO almost certainly this year will end with losses for the investor, the time has passed when it was possible to make good money on ICO.
