a store of value doesnt drop 80 percent during a year, for me it looks more like a fanatic cult group of sectists.
i think bitcoin's volatility will wane eventually, perhaps decades from now. the 80% + drops are a function of its parabolic growth cycles. so right now, it doesn't act like a store of value because it's so speculative.
if bitcoin is alive and well in 50 years, it won't be so speculative and it probably won't be experiencing bubble periods (or 85% corrections) anymore.
