The clock is ticking for Bitcoin. My main ideas about a big drop (retracement) is always in play. We have probably seen the last rally of the year, and there is not much time left. Year is ending, and of course there is no liquidity in the market during this days. The whole market is boring, big players are probably out. And when liquidity kick out from the market... you know. It's just matter of time, i think as soon as BTC will broke down my trendline it will start a vertical drop
