Right now there are many ICOs coming out, is it really safe to participate in any of it and spend that much? In participating ICOs I have high hopes that these coins could be the next Bitcoin or other currencies that are really going up in the market.
I guess it's not safe to participate in ICO because we do not know the funds we have invested will be used for the new coins or not because the system is not clear. Pay a lot of people who already invested in ICO and found that they lost everything and got nothing.
It depends on what you are talking about.
If you mean investing in ICO (buying tokens) then it is really risky. It often happens that during the pre-sale tokens are selling at very high price but when ICO ends tokens suddenly decrease.
But if under participation you mean working in ICO (Signature, twitter, Facebook, telegram campaigns etc.) than the worst result: you don't receive your tokens but in fact lose nothing (only time) - so its safe.
