Hi guys

Me and a friend are considering buying the new kncminer Neptune. It's priced at $13k with minimum 3000GH/s of hashing speed.

How many bitcoins could we realistically expect to get from it in say six months if we keep it running 24/7? How long would it take to pay for itself if we assume bitcoins will be at $800 in six months.

Would we be better off joining a mining pool or do it on our own?

Or maybe it might be better to buy equipment for the same amount and litecoin mine instead?

Cheers
