Hi,
I think some people need more patient with their investment in ICO.
Check
www.icostats.com. The profits are amazing!
You also need to have a good project for profits..
Purely depends on the project, a lot of people will invest in an ICO simply to make a quick profit when it hits an exchange, they will make their profit but if you as an investor actually believe in the project then you should be looking to hold for a bit longer until you at least give the project a change to start.
