Is history repeating itself in BTC?

Based on the monthly timeframe with the aid of Bollinger Band, BTC had been very overextended. A healthy price rally should be staying IN the Bollinger Band region where it gives a steady growth.
By comparing the price movement fractals from 2017, we are also over extended out of the Bollinger Band region and the next move is a hard correction!
RSI is also indicating BTC is currently sitting at overbought region.
I predict BTC will fall and touch the red median line and rebound from it.
**I may be wrong!
