this is very through. many projects will want to take advantages of alts season to enter the market. But in my opinion, a solid project needs not wait for bull season before launch; many project were launched during bear market and they do well.
It's been evident from 2017 ICO which many projects before bull run really do progress well and it's also true that many projects fr 2017 failed due to its hype only in making their projects release without any concrete plan just joining the bulk of ICO projects during that time, we will able to see that only few lis still visible now 3 years ago.
