'Bitsquare is open to add any altcoin which requests to get added to the supported crypto currencies. Adding does not mean any endorsement and as long as it is not a clear scam coin we accept any coin which fulfills our requirements as defined below.
Please note that we cannot add all available coins by default as it comes with some effort for us (input verification for the coin address, add search option if the list gets too long, do basic checks if it is not a clear scam,...).
Beside that it would be pointless to add coins which never get used for trades because they are not actively maintained or used anymore.
Here is a basic rule set to make the process and requirements transparent:
If the altcoin has a market cap or trading volume in the top 10 range we might add it without further requirements.
If we think that an altcoin has some outstanding novelty or properties we want to support we might add it without further requirements.
Other altcoins need to fulfill the following requirements:
The requesting person needs to be associated with the official coin (use an email address indicating that you are from the team)
They need to add Bitsquare as official exchange to their webpage.
There need to be an active block explorer available.
They need to send an example address of the altcoin.
The ticker symbol does not conflict with any Fiat symbol (Check here:
https://en.wikipedia.org/wiki/ISO_421727).
The requirements to add the coin does not cause extra effort for Bitsquare like adding additional input fields (e.g. if the addresss alone is not sufficient for the trade).
They need to provide the rules for validating a correct altcoin address. Input verification for the coin address will be added soon and we would need to get the specifics of a altcoin delivered from those who are interested that it get added (if the one who want to add a coin is not a developer he needs to request those information form the altcoin developers - Bitsquare will not do that task). A pull request with actual code contribution is preferred over pure text based information.
There need to be some trading activity. If for a period of 2 months no trade activity is visible that coin might get removed again.
If a coin represents political values which are diametral to Bitsquare's values we reject it (e.g. fascistic, racist,...)'

Any thoughts?
I think Bitsquare is an excellent addition, but like Sirsmokesalot, I am slightly queasy after seeing the up front demands.
