i was thinking about gathering 1-2btc and 1-2k$ and to start an exchange service with 5-7%
do you think it would still be profitable? with coinbase and localbitcoin and all..
It can be profitable if you find buyers and sellers at the same time, it depends how do you think to start your exchange service, selling and buying locally or how, some people don't care too much about small difference on fees, they only want to buy in cash and avoiding online ID verification.
i dont know what it is because i never used it before but you cant tell people what they have to do they also need to make their own desisions...
