It is hard to say which is good and my favorite coin, I would still recommend Bitcoin, Ethereum, Ripple, Monero, and EOS.
However, with deep in-house research, you can unearth some truly interesting and with huge potential projects. Tho I am leaning now towards projects that do not have any premise, instamine or founder taxes.
However, the question was what is the best ICOs to invest in. I will share the projects that are still in the early stage that I think is currently at the top of my lis:
1. BitTorrent
2. Marconi Protocol
3. Historia
4. StarkWare
5. Oasis Labs
