Thanks for sharing your experience. I have the same opinion about ICOs. There are so many ICOs today, despite the fact that all initial offerings are high-risky investment tools, 90% of them are scams. So it's more likely that investing in ICOs is a way of loosing your funds. Just pure statistics.
Meanwhile IEO are not that scammy at the moment, but still provide good profit for investors.
I guess ICO could be safe and profitable but only when scammers will "forget" about its existence
