I bet we will see better and baddass projects in 2020 simply because bitcoin halving is 2020 ,since what most devs care about is market condition and fear of dumping there tokens 2020 will be a better target for upcoming projects and that doesn't mean there won't be scam projects too ,profits is all we care about isn't it?
When bitcoin halving in 2020, it will affecting the price of the coin surely. But why do you think 2020 is the best year for ICO ?
I think scammers will keep creating scam projects to steal people's money. But we won't fall for it if we stay alert.
2018 was not good, and there is no bull run since that time. I believe there will be a green market again, but we don't know when.
