Ixcoin has a big advantage by being a bitcoin clone. One example;
The iguana project by jl777 is a drop in replacement for bitcoind. It is also a multi coin wallet with decentralized trading. Ixcoin will be very easy to add to this wallet. Ixcoin will even be easier to add then litecoin and namecoin.
A big selling point should be, if bitcoin can do it, so can ixcoin.
Yes, and eventually Bitcoin will become too big, cumbersome and expensive. It's block chain is already pushing 80 GB. And how much more can devs increase the transaction rates?
So where is a good place to turn if you don't want to loose all the Bitcoin plugins... the Bitcoin clone.
