In my experience of trading and investing for 2 years, I recommend investing in bitcoin and holding it from now on. Bitcoin's price has dropped quite sharply and is near the bottom, so buying it from now on is likely to make more money in 2020 when Halving bitcoin takes place.
Why should we not invest in ICO? because when the bear market comes, we see lots of scam projects coming up and lots of bad projects. So investing in ICO right now is risky.
