BTC could be $20,000 and you still might not be profitable miner.
I dunno, could you explain the situation to me? Astronauts mining bitcoins?
Think very high difficulty. Think Google and Walmart setting up datacenters for bitcoin mining with onsite power generation. Think oilsand plants in northern Alberta using their cogeneration plants for bitcoin mining (using ASICs of course (more efficient than FPGAs)). Think thousands of transactions an hour, pushing home Internet connections off the network (must pay $300/month or more for business Internet).
