1. Attract investors with good discount price
2. Make enough money from IEO fund raising
3. Use very low fund to list on shit exchange
4 Abandon the project slowly
This is all planned from the beginning....
Now the question is which developer doesn't know that listing on low exchange won't do any good? are devs that stupid? no they are not,infact they are the ones that understand more about crypto that any other.
Yes that's true planning is several months before, but there are a lot of instances that they are in a hurry to create crowdfunding, even to the extent of copy-pasting their whitepaper and doing photoshopped their team members and they include experts without permission.
At this point in time, you cannot pull out a scam project without making your project looks very good in the eyes of the investors.
