You are right but there are ICOs that are worth to invest too so it is fine for as long as we investigated the project that we are investing at , for as long as we know the things in that ICO and we are sure that it is legit one, because if not then we will just waste our time and effort again, so better to do thorough research first.
Lately, even though you researched a project completely, it passed all the stages and produced a coin on an exchange - the price decreases twice. And it is not about raising funds methods but preparedness of a team perform all the necessary measures for complete readiness of a product.
Well it depends upon the ico. I believe that we need to choose good ico for good. I believe that investing on good ico today is really good because we are now on the huge dip and we can maybe earn on it, because the ico price may be affected on tge huge dip that we are nlw experiencing.
