Solo mine = the better option.
There is a pool designed to function like solo mining where you keep your voting rights, yet it has the variance reduction in payouts like a pool.
P2Pool.
P2P mining makes no difference.
P2P miners can mine without the blockchain files on their computer. How can their vote without the transaction records.
Umm no, you are misinformed. P2Pool miners need a full copy of the block chain.
