I think yes some of ICO is profitable to invest because you will see to them or the team if they do their best to make the project be successful. Even the situation in the market now is bearish many people still find a good ICO .
seeing how many ICOs are currently running, of course there are some ICOs that are still profitable, even when the ICO runs according to the roadmap, and has prices according to its ICO, of course it will be very profitable. however, for now, it's quite difficult to get a project like that.
It turns out that investing money in bad projects is simple, but not to get into good ones, therefore the topic of investing in ICO is not relevant now, since it is unprofitable.
