every single day ICO projects always appear with their respective advantages. but in fact, many are experiencing failure in the end. they just waste time and spend money to advertise? how about you're opinion 
Icos are investing at your own risk although there are real project with real roadmap platform we should diligently search if the people behind that project are indeed capable to push though with their roadmap and will not run away or leave after they got your investment
and if we decide to invest our money in ico, then we need to know that we cannot always make a profit in the end because we need to make sure that we know all the info about the ico and then we can choose a good ico with the good project. there is nothing we can do to stop ico but I think the government can stop them or by controlling every ico that wants to launch. I think the government will make some regulations for this so the ico need to understand that they cannot break the law.
