is there any mastercoin wallet?
im trying to sell my master coin since they worth like 180$ each, but the only site trading this coin is masterxchange and he asks for my wallet adress if i want to deposit coins.
can somoene help me find a wallet or find a way to trade those coins without a wallet (right now my coins are storaged at the pool)

Hey everybody , this is my first post, sorry for my english.
im a new miner and i have a question, does the pool im using effects the coins im earning? there are better pools then other?
is it matter what pool i am at?
