It has more to do with luck as opposed to skills, to be honest.
After the roll-down, I double-checked the UVXY volatility chart,
and realized its IV was no longer overstating HV. In other words,
there is not enough short-term premiums to squeeze,
with respect to the risk I am taking.
I was probably too aggressive and greedy. It could backfire
if VIX spikes again.
Rolling down to only ~35, rolling out for one additional month,
or closing out half of the positions, might have been a safer trade.

: high hand call. 这把你赚爽了吧。其实在顶上还真的没有什么低风险能赚钱的操作,
: 只能闭着眼睛烧靠,买put简直赚不了啥

Stock prices follow log-normal distribution;
they can only drop to zero, but can shoot up to infinity in theory.
It is possible for UVXY to shoot up 100x if the market crashes.
Many people are betting on it, so they bid up the call prices on all strikes.

Historical volatility (HV), or realized volatility
is the actual volatility computed from stock price movement.
Implied volatility (IV) is computed from option prices
based on the B-S options pricing model.
The main argument of the short-volatility school is that
IV usually overstates HV, especially in high IV environment,
rendering short-volatility statistically profitable.
