Yes Ethereum is unlimited in total issue. Leave well alone I THINK.
Litecoin is the most exciting coin. Cheap with cryptography just like Bitcoin (but with different mining proof of work) although 4 times as much in issue.
At some point Litecoin will get adopted JUST LIKE BITCOIN and explode.
First coins issued will always be the most valuable I believe.
The forks of the Bitcoin blockchain are fascinating creating new Cryptocurrencies overnight with billions of dollars market cap.
I see the forked coins as dividend income tax free on my Bitcoin.
