what is the cost of building a YAM like Defi project?
First - do you want to build it to run, or sell? That will influence the amount of polish, features and security you want.
Second - are you going to do it legitimately. or try to embezzle funds to make a living? That will influence the amount you'll spend on reports, client access, provability, etc.
Third - what do you expect to pay for developers? $1/hr? $10/hr? $30/hr? Tokens?
