My dreamcoin is something that I can just click and pay using it and be received anywhere in the world with no or low transaction fees and be fully convertible to and from fiat.
so.... bitcoin!
i'm still waiting for the Ultimate AltCoin to come along
i would expect this coin to be advertised for at least 1 month b4 its released for mining
a good solid infrastructure ready from the start ( exchange, marketplace, community, charts, the works! )
this coin must take all the little improvements other altcoins have and add some of their own,
MUST solve 1MB TX limit scalability issue...
