My toddlers are already involved. They even refer to it as "the Bitcoin miner" and like the heat it puts off. They also say "It's Bitcoin time!" when my phone alarm goes off.

EDIT: How times have changed... When I was a kid, sometimes I'd eat cereal in front of the furnace in the winter, but kids these days can get warmed up by a Bitcoin miner.

EDIT 2: Ha! I just lined up a free, tiny miner to use as a nightlight & white noise in their room--pointed to my BTC address until Kano codes the dust payment capability. Start 'em young!
