is your goal to make the money you lost back or something else?
If it is simply to make the money back why would it make sense to trade a stock like SNTL for 11 years (as you said) for just a 10% spread.
IF the goal is to make the money back there are thousands of other plays out there. Just seems counterproductive to try and make money back 5% at a time, while in the mean time clogging the ask and flipping a tiny spread.
