You may go for running a local exchange for your countryman as a trouble free crypto exchange for world wide people. I am not aware of where you are from but this is the business being missing out in entire crypto space and also this will work as a very good promotion for bitcoin among new people. This may work even for highly developed country also as people want to have a trusted know exchanger as it might give them extra credibility toward crypto space.

For an usual exchange, I suggest no-KYC for ever kind of promises will make you popular in short time frame itself
