I've been observing the market for a longtime its now about a year . in your opinion, what is main culprit of decreasing the price of btc so dramatically ? Are you expecting the price to go up dramatically soon ?
Very easy explained the price is determined by the demand. If more people wants to buy than sell, the price will go up. If more people want to sell than buy, the price will go down. This is how it should be and this is one of the things people usually like about Bitcoin and cryptocurrencies.
