why would someone switch from a long known exchange like binance/coinbase/etc. to some brand new exchange?
many factors can be considered why there are people who switch to new exchanges. some of it may be its availability in the area, convenience to use, new features and etc...
Overall i find working on a new Crypto Exchange a waste of time, money and effort unless you have some truly insane idea.
not really, an insane Idea can come once you have started your business or in this case crypto exchange. as long as there is a market and it can be profitable it is not a waste of time. it will only be a waste of time, money and effort if you don't properly run your business or you are missing something that other businesses have and you don't.
