Bitcoin can really compare to a roller coaster. Like today, the price of the bitcoin is continuing to go down. It is really hard to predict if the price of the bitcoin will go up or go down. If we look to the chart of the bitcoin we can see the pattern like a roller coaster because of the increase and the decrease of the price of the bitcoin.
If you are a trader you should take advantage on the roller coaster movement of Bitcoin, bécause it would create an opprtunities to buy & sell.
i find that selling is harder than buying. it just seems like the lows are easier to pick out than the highs.
