The beauty of bitcoin is due to its volatility. If you can remember last 2nd week of November, it plummeted to 5,600$ after reaching 7,600$ and then had a bullish run up to 17,000$. Yes, btc trading is hard for short trades but my tip is to take profit around 3% to 5% to lessen the risk of losing. If you are in long term trading, just hold your position, btc price will rise eventually.
