49% are 50 year olds investing into bitcoin, and the other 49% are 15 year old kids who either scam or think they are captains of industry. The other 2% are the 30 something libertarians.
LOL
Makes me wonder about the average age of miners.
The price of ASIC mining hardware might exclude some of the younger aspiring miners, although BFL Jalapenos are within almost anyone's budget. Script kiddies would probably have to make do writing mining trojans.
As for us old farts, we can usually afford the hardware but by the time it ships, difficulty levels have outpaced our investment. Until my $650 BFL LS arrives (hopefully before autumn) I've shut down mining for the summer. I heat my place electrically and the savings on my heating bill made GPU mining marginally profitable this last winter.
