my first question is WHY?
there are so many exchanges out there already, what are you planning to offer that these dont have already?
Because we think lots of those existed exchanges have bad user experience, it makes our project has a slightly chance to beat them and we'd like to give a shot. Actually I think our biggest challenge is not technical but
to convince people believe this is a reliable exchange and willing to come. As you metioned about get Bitcoin at one exchange and transfer to another exchange to trade, I guess because most big exchange would avoid exchange between various electronic currencies and legal tender to reduce legal risks.
A good point, how to convince people?
Just provide more information about the exchange, especially where is it located? Can people visit the headquarter if there is a problem?
The most common problem for people who deal with exchanges is the ticket waiting to be replied for weeks or even for months.
If you can convince people that Bitpaction exchange will never have the same issue, people may be attracted to try this exchange.
Another thing to note is fees for deposit or withdraw, as the current network for bitcoin requires high fee to transfer bitcoin, you may want to set a flexible fee for withdrawing bitcoin.
Invite user to visit our headquarter is such a brilliant idea, I promise we will do this while our exchange running smoothly. We are cryptocurrency enthusiasts ourselves, so we are very concerned about the advantages and weakness of other exchanges, to avoid those issues you mentioned of those exchanges are important for us. So please trust us, we will do this well.
