is it possible that a large asteroid hits earth? yeah

However, you can't trade based on these possibilities.

My take: reduced oscillation thesis

$32 peak, correction to $2 (94%). Bottom just 6.25% of the peak.
$1176 peak, correction to $175 (85%). Bottom just 15% of the peak.
$19760 peak, correction to? Linear progression of the trend suggests that ULTIMATE low would be $7113 if my reduced oscillations thesis is correct.

However, it is entirely possible that we will double peak like in 2013. In that case, the ultimate peak would be $50-132K, then a long bear with a bottom at 36% of the top give or take.
Therefore, if we go down to $7K relatively soon, then it would indicate that a bull market is about to start.
In an alternative scenario, we will bottom higher, then go to $50-132K for an ultimate bubble.
