I use an old school proprietary hand analysis system that does very well at establishing major support and resistance. This allows for very fast notification of a trend reversal. Having watched BTC for a year, I find the weekly chart is the best for this. Based on this, price just bounced off major support. Until it closes on a weekly candle below 6870, in my analysis it's a buy. With all trading, unexpected new fundamentals can cancel technical analysis. However, the odds are, until BTC breaks and holds below 6870, we will see it go back up. So great time to buy is NOW as you can use a very tight stop! Good luck!
