At this point, Poloniex and Bittrex International are the only decent exchanges that list MAID. If you live in the US that limits you to Poloniex. I’m curious as to what level (i.e., release of Fleming, Maxwell or Beta) needs to be reached before Bittrex US would consider relisting.
Since Binance is following in Bittrex’s shoes by splitting into US vs. non-US exchanges, now might be a good time to approach them.
Also, Kucoin seems to be a decent exchange. I’ve also heard positive things about Huobi, and a friend of mine is a strategy director at Kraken. Has MaidSafe approached any of these exchanges?
