$800 for 1 hour and 24% for two weeks - the bitcoin reminded of itself

The cost of a bitcoin reminded investors how volatile it could be. Yesterday, the bitcoin lost $800 for an hour, momentarily reaching $9,000 a coin. Subsequently, the bitcoin recovered some of the lost, returning to levels of 9,300 dollars.
According to CoinDesk, the cost of the bitcoin fell to the lowest value of $9,075 before it recovered.
The yesterday's depreciation in price was exceptional as the cryptocurrency was traded at about $10,000 earlier.
In addition, it happened on a day after the fall of $1,000. Or, the investors were reminded of a very painful way, how volatile the price of cryptocurrency might be.
However, the decline in the bitcoin has not been limited to the last two days. The cryptocurrency continued its way down and was trading this morning at $8,700 a coin. Thus, from the beginning of the week, the largest digital coin lost 24% of its value.
According to market observers, the depreciation of the bitcoin on Wednesday was predetermined by several factors. First of all, the news that $400m worth of bitcoins were liquidated by a representative of the failed Mt Gox stock market, which has flooded the cryptocurrency markets.
However, it is much less clear what caused yesterday's $900 depreciation, in a very short period of time.
More and more analysts are predicting a further depreciation to $7,000.
