Its called speculation (or gambling). It is an addiction. We have banks, and markets set up to legalized gambling, with no underlying value. Welcome to the human race.
See the tulip bubble, housing bubble, etc...the asset can never go down! Until it does...

Right. Still though, can anyone chime in with some calculations? If this miner will never mine as many bitcoins as were spent to buy this thing, what dies it matter if bitcon will jump to 10K per unit? You still lost bitcoins in the end??
There's gotta be a catch here.
It's simple; if that miner that cost you £2,800 only mines you 1 BTC before end of life and the value of 1 BTC rises to £20,000 sometime in the future, then it was worth all the effort.
