It's an interesting idea, but I don't like the example challenge:

_Binance, one of the world's largest cryptocurrency exchanges, is considering banning US traders in an effort to gain favor with the US government and to improve its reputation as a legitimate enterprise. 

Design a new product for Binance to to make up for the loss of revenue (approx. 15% loss) they will incur from this move._

Why would a company think this way? Take your best opportunity, period. Don't try to make $5 more per month in income because your monthly gas expenses just went up $5 per month.

Half of our job is defining the right problem, and this is not the right problem. The only thing this example does for me is show that I wouldn't want to work for Binance.
