1. Good projects takes time to build, they aren't rushed so they take lots of time in development
2. Real working products from companies that have been in existence for years are way better when they implement blockchain tech in their company it will work out
3. Its red flag to projects from companies that starts on crypto from scratch, meaning that they are able to be where they are today with crypto.
Based on past performances of many start ups, I have to agree with the above.
No. 3 is all about promises and we should all know by now that empty words are not worth a penny. Ideas are good but a relevant working product is what it takes to survive in today's competitive crypto market.
