According to very long-term Fibonacci time zones, BTC will experience an inflection point by the beginning of November, thus finishing its current long-term rally. The last top in this rally would occur just before that change in the major trend and would probably locate between $5000 and $8000. Daily RSI and MACD show enough room for this final shot. The ensuing crash will be identified by a fall of 50-66% of the price at the top.
