Here is my calculation based on past performance of LTC.
LTCBTC last time lowest point was 0.005, then 5x to 0.025 in about 83 days, 50% drop to 0.013, if it does 5x again, next target is 0.065BTC.
LTCBTC last time lowest point was $36, then reached Fibonacci projection of 4.0 which is $420, if it does 4.0 again, next target is $1646.
$1646/0.065 = $25323 USD/BTC, and if we use 83 days to calculate from the lowest point to this target, it should be right around the end of May.
I don't know if I am making sense, but the math does not lie. All we rely on is let the history repeats itself. :)
