So you'd say it's better to stay away? My main concern is compliance with US gov (I am not american or european) but anyways they are always behind everyone.
If your country is legally fine with the projects you are building and it certainly lies in compliance with your laws,US or any other government should be the least of your concerns.You're not Pablo Escobar,you aren't stealing money out of American Pockets.
You could be swamped with hack attempts and support requests when you were expecting to set your bot and go to sleep. Customers are stupid and nervous so they'll always be messing up and looking to you to solve it.
Well,running an exchange successfully isn't a one person job.Buying better servers/programmers to code the back-end removes 70% of those problems.As far as support requests are concerned,they should be taken seriously.
