Regarding the Nvidia miner, the code (still WIP) is available here: https://github.com/LIMXTEC/xevan_ccminer. The miner has not been compiled for windows, and requires testing by people who have Nvidia graphic cards.

It is never too late. Mining alone is a long way to a masternode, buying it from an exchange will save you a lot of time.

You probably meant volume or something similar. I find it useful to get BSD listed on more exchanges, regardless of their volume.
