I'm not sure if 2020 is a good year for the ICO. every year is a good year for ICO, I think. because 2020 is the year of bitcoin. not ICO. although there is a relation, if bitcoin is good, then there will be lots of good ICOs popping up. but, it shouldn't be a problem. If indeed ICO is good, they will appear at any time.
I agree with you 2020 will be the year of Bitcoin. No need to think of anything else, if the price of Bitcoin rises then the token price from ICO coins will also rise too. Everey year is a good year for ICO, depending on how we choose good ICO.
