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 to those who start 3 years ago.
Most of them are already dead long time ago. Only few survive. Because most of them were launched for the benefit of the dev team, collecting money from naive investors. Empty foundation, no actual development and the problem was a lot of them had anon team. So they can easily disappear without a trace along with the money collected. So as long as there are naive buyers in the market, there will be scam projects in crypto space. Just look at the bounty section and there are so many projects being listed every day and most of them, even their bounty hunters are being screwed.
