BTCUSD is within striking distance of the 1.618 extension inversion as measured from the Dec 2017 high to Dec 18 low. A modest fib pull back to the .236 would give us 40% decline. The measurement lines up nicely with the ascending long term trend line on this log chart. I am extremely bullish on Bitcoin, but its good to keep in mind the ridiculous percentage range BTC has. So in short we may see 30/35k again before we see 100k.
