You are being a bit too smart-ass here.

Of course, they have a considerable goal that involves profit maximization, but how they achieve such goal - the means to the ends, is part of the question.

Do you really believe that if most other exchanges have fees below .25% then it is obvious that merely raising the fees to 1% is going to achieve their objectives?  If that were true, then a lot of other exchanges would have already gone down this supposedly obvious path.

There is a reason that coinbase keeps its maker trading fees at 0% and its taker trading fees at .25%.  Maybe in the future they will increase their fees, too - however, they have had 0% maker trading fees for several years.

So, you know as well as me, that you were not being genuine in your answer and you were not really grappling with the real question, right?
