I am sure that the crypto-currency market is manipulated in order to expel inexperienced traders, thereby making money. Do not panic.
One of the concerns about bitcoin is that prices are very volatile, rising very fast and also falling rapidly. Some of the factors that influence bitcoin price movements are news, whether it's from online news, TV, Radio or negative or positive newspapers. For example, when there was news about the ban on cryptocurrency advertising, this sentiment triggered prices to fall quickly. Conversely, good news makes bitcoin prices rise.
