Bitcoin, just this week, dived from about $47,000 to $43,000 (today's price). Why did this happen, you ask? Well, there is no exact pinpoint reason. Based on our research, it seems that a bunch of Bitcoin Whales (people that hold a very large amount of Bitcoin) decided to sell their Bitcoin - adding to the supply of available coins for purchase, therefore lowering the price per coin.
Because all altcoins (alternatives to Bitcoin) follow the Bitcoin price trend, this dive also caused all altcoins to fall in price - even more than Bitcoin did, since altcoins have less holders/investors than Bitcoin. Of course, we don't like seeing the price of something we invest in go down, but, we try not to look at it in a negative way. When Bitcoin goes down, that doesn't mean you should "panic sell". In fact, you should never panic sell, because that usually just results in an even bigger loss. Look at it as an opportunity to buy more Bitcoin. The price went down, so now you can buy more Bitcoin for a cheaper price, and when the price goes up back, your Bitcoin will be worth even more. The saying is, "buy low; sell high". Buy Bitcoin when the price is low, sell it when it's high, and repeat.
Don't be surprised if Bitcoin drops below $40,000. It happens - the crypto market is volatile. But, as long as you hold and don't sell, you will make a great amount of profit.
