Hate to break it to you, but we're all gambling on the future of bitcoin. It could crash to $1 tomorrow on some type of devastating news, and a lot of people would lose a lot of money.
Not true, I have mined/earned all my
BTC.
I lose nothing if
BTC plummets.
I use the electricity that comes free with my rent.
I hope
BTC flourishes into a useable currency,
but if it doesn't I will not lose anything.
