This is true of Bitcoin, though there is also a chance it goes in the other direction.
It's funny you should use the house example, since in 2005 I bought my first house for around $250,000 and three months later the house was worth less than half of that. It contintued down for a while and still has not risen above that initial figure. We no longer own the house.
The experience has definitely soured me on the investing advice that was given to my generation.
