Bitcoin has fallen by more than 56 percent since the turn of the year, after peaking at nearly $20,000 in December 2017.
CoinMarketCap price charts show that bitcoin has been falling for weeks, though this latest crash has been blamed on mounting confusion surrounding the Indian Governments stance on cryptocurrencies.
Bitcoin falls as many investors sell Bitcoin at cheap prices, causing Bitcoin's price to fall continuously. Then indeed a lot of countries that prohibit the use of Bitcoin, of course, this will cause Bitcoin users who live in the country does not use Bitcoin. Actually, a lot of factors that cause the price of Bitcoin fall and this is all I know.
You're absolutely right. When an initial dip is followed by a massive sell off, it will cause a continuous dipping of price. That is what actually had happen in the market when an initial dip caused by fake news or FUD's, small bitcoin holders are starting selling off their coins just to save their investments as panic sell off was done. And this would let them sell their coins at cheaper price. Thus making the market price to go downtrend.
