It looks like the cap is already high.
Compared to what???
The solarcoin cap is currently around $6 million, but that is just pocket change compared to the bitcoin cap of over $28 billion. Even litecoin has a cap of more than $1 billion. So a cap of $6 million is quite small. When this coin hits a cap of $60 million, then you'll be kicking yourself for not getting in the market sooner...
