This is really a good question. To check out what a good ICO is,
1. You first have to check the team associated with the ICO. An ICO on health should have health professionals in fact a Doctor who backs the project.
2. Read thoroughly the whitepaper and check out for the problems identified and the solutions they want to bring on board if it is achievable
3. Also check for the soft and hard caps. This will enable you to know whether their project will be successful or not.
4. Also check for the roadmap what they want to do in the future.
5. Lastly is their coin a ERC-20 token? You need to also check that.
When all these background checks are made you will be able to know the best ICO to invest in.
I cannot always rely on the points that you are giving because scam and fake ICOs are too good to be true this time. In fact, fake and scam ICOs do have very impressive website designs, roadmaps, advisors and all people and staff behind the crypto projects.
That is why spotting fake and scam ICOs are very difficult this time and if I truly impressed by the crypto projects, I will then wait for them to hit crypto exchanges especially on coinmarketcap.com so I could hit invest and wait for my earnings.
