Historically it does appreciate in times of uncertainty. But even with uncertainty, it may appreciate, but I don't see any reason for it to skyrocket. Cryptos will likely eventually be an easily accessible safe haven for money or currencies that become at risk of a crisis or hyperinflation.
Even in times of uncertainty, people flock to gold. Silver may be a precious metal, but it always plays second fiddle to gold.
There can be no reason why it will skyrocket (unless it finds some new industrial application).
