Ill still be doing this if the difficulty hits 500 miilion. Im not in it for money
Can't compete with that
Then again, it does make the network more secure. If everyone just quits mining the network becomes susceptible to forging attacks
Thats part of my reason for being involved. I really want to see bitcoin as a currency (or commodity, depending on who you talk to) flourish. If all it takes to put people off being invovled is that its no longer profitable to mine, because some people with deep pockets (and perhaps with an interest in seeing the ideal disappear) flood the system - then whats the point? If i were a large economy and felt threatened by bitcoin I would do my best to make sure people found no reason to mine through lack of profit. But if miners are here without the drive of profit, then the 'flood the market' move is, to say the least, stale. The ideal stays alive and presses on.
I know a lot of people out there who made this ideal get off the ground invested a lot of money through mining to get it going. I cant thank them enough. I'm sure they will make more money in the years to come, but I hope the ideal of what bitcoin is about stays with this forever - long after some people give up mining because they no longer make a few bucks a month.
