To address the technical issues and without giving out too much details, the exchange wouldn't hold any of the money or funds itself. Rather, you as the client would give permission to move money to an already predetermined address which allows for multiple levels of permission. The exchange has the ability to notify you there is an exchange ready, request that the funds be moved, but you must confirm to move your money anywhere.
Like at the Bitsquare, lol.
Without you and your private key, your funds don't move (your key stays on client-side of course)
Lol. this scheme is being used in every centralized or decentralized exhanger.
We hold no money, only connect the people whom want to exchange.
lol, that's mean that your exanger is centralized. In decentralized exchanger this infirmation is kept on the client's computer (node). And this complicates such exchangers, bacause node becoming very "fat" (it's holding every information from the system, like Core client).
The fee is to cover the network cost and pay the developers/investors.
you mean that you have centralized exhanger. in decentralized exchanger there isn't any "network cost". Please, watch my statement above.
The fee is to cover the network cost and pay the developers/investors. How and who (pseudo-ID) the fee gets distributed to is all public, but as to the identity for whom they are, that is not available. What's public is the % of the fee that pays each dev and potential investors. This can also be subject to change, and a dev or investor can give or sell their shares of the transaction fee if they so like. This would be projected and be public on the blockchain as well, to keep integrity in the service.
Strange. Sorry, but today i don't have much time to explain your false. Maybe tomorrow i will try to do it.
