I thought it seemed like a short time to develop from start to finish. Unless there was a short cut since they know the code?
My concern was that the timeline seemed unrealistic like it was guesstimated and not estimated.
It is why I asked if they needed a week to provide a real timeline and cost analysis.
With my experience of estimating projects you can come close from experience and rough ideas. But until you draw(vision/plan/details) the project and list out all components you cant make an accurate estimate.
Edit: I wasn't thinking they would be able to write test and implement anything in less than 4 months. Todays date Feb/07/2019 I was thinking they are only estimating writing the code?
Good points.
I'm thinking there is a connection to bitshares many are not aware of as well.
Maybe things have already been largely developed. Kinda like how @dan responded to a lot of the fiasco here lately.
As for Bitshares, we are talking about the same players from there that are doing development, etc. on Steem. Can't imagine they don't have a grasp of the stuff already.
