Just throwing this out there, but
At any point in Bitcoin's brief history if you had taken the money spent on mining hardware and bought BTC instead and held it you would be better off now.
If everyone, or even a majority, had decided to just buy instead of mining, the supply would be much less, the utility as a currency would be much less, the demand would be much less and the value would be much less. Also it would be freakin' boring.
Running hardware is fun, sure... To be honest, the initial fun wears off pretty quickly.
I've gotten almost daily enjoyment out of finagling and maintaining mining hardware and software for going on six months, with less than $1000 total spent (and most of that returned and reinvested). For me it's comparable to the guys that buy and restore old cars. Sure I could have doubled my money by just buying coin six months ago and selling it today, but what fun is that? How is the network, or even the *concept* of Bitcoin in any way benefited by my doing that? I profit from someone else's work and someone else's greed and meanwhile nothing actually gets done. Not buying hardware was never even an option.
