It will (probably) get below $2 because at $2 (or even in principle at $1.01) supply will keep being produced essentially without bound as the graphs in this post illustrate, until there is just no more incremental demand to keep buying more of of it, and then the price will fall.
Look at the price chart for last year. Just as it has proven that it doesn't reliably hold a peg, it is also proven that it is possible to return to $1 after being too high (once supply with its slow-but-relentless climb catches up).
It all sort of works, but not consistently.
