server fee is not the question
LOL server fee is a question to maintain an exchange you need a solid server infrastucture to manage the traffic , you can't build that with a 50$/month server you will need a solid infrastucture IMO if mscolec can't pay the server fee he should sell a % of the exchange to someone that can invest and sponsor the server infrastucture .
The server is $40 but I have so many server on my account. However as soon as the exchange open and we have to get someone to run the exchange until it's Decentralized
