I have written an article on BTC history and how it can impact it's future. Link is below - but we must be cautious as a lower low may be coming after this current upward run which is nothing but B of ABC ZigZAG. as @Haejin brought a number $16k or so. it's indeed a calculated number. Sub wave a of B went from 5900 to $11800 a gain of $5900. the WAVE B is flat type so it's sub-wave c can be 165% of sub-wave a which is 1.65X$5900=$9778 so C can get up to 16K. but after sub-wave c completes we looking a major major C wave that can take BTC to 2k-$2500 range.
