Now that Masterxchange is closing, we need a new exchange for Maidsafecoin. Bittrex for example. Just imagine for a second that something happen with Poloniex, just like happened before with several exchanges, and everybody loses all their bitcoins and maidsafecoins inside Poloniex. It will be a tragedy for Maidsafe, we cannot depend of one exchange.
Something like that happened before with another coins, NODE for example, it was only traded at BTER, and BTER was hacked. NODE was impossible to trade for more than one week, and the price went down like 500%. All the buyers with opened orders to buy NODE lost their bitcoin that were supposed to be converted onto NODE, and the market was destroyed.
It’s risky deppend of only one exhange. Maidsafe shoudl contact with another “big” exchange, Bittrex is a good candidate.
