I was thinking about altcoins and how there are so many and a majority of Altcoin users hold more than one coin. My thoughts led to an idea about a multiwallet but unlike others it could be a wallet to hold all coins.
So the idea would be this you have a multiwallet that contains the abilities for many coins. You have addresses for each but also a wallet multi address and say 2 users both use multiwallet: User A likes dash and user B likes Monero, they agree on an exchange of an item for 5$ worth of coin, using api's from poloniex or cryptsy the wallet stays up to date on the prices.
User A selects his send coin (dash) and types the amount of usd equivalent to send (5$) to User B. User B has selected his receiving coin to be Monero, User A sends to the Multi address, 5$ worth of dash, it using a similar software like shapeshift.io the User B receives 5$ worth of monero.
This can only be done between users of multiwallet but all currencies would of course have their own send and receive with their corresponding addresses.
Does this seem to be like a possible thing or am I missing something here?
Would you use this?
count me in, i think large exchanges would love this, just assembling all the coins and their blockchains maybe a mission
