Personally, I prefer buying BTC, because investing in ICOs is currently very risky, and almost there aren't promising ICO projects during the few previous months. Bitcoin still the most stable and promising cryptocurrency right now, and its price is expected to increase highly in the future, so it is better to buy it while its price is affordable.
at the moment I think it's more potential to invest in bitcoin, ICO popularity has declined because of the many scams. but the greetings of bitcoin investments are aimed at long-term investments and I also don't recommend ICO investments for now
What you said is right, we have seen many scam projects launched in the form of ICO and collected a huge amount of funds by the active members. It makes many community members are fed with the ICO and started investing Bitcoin, Bitcoin always gives good returns to the investors who patiently waited.
