When investing in a crypto currency it's price is at first speculated on since everyone wants his or her cryptocurrency to increase in value over time. There are some risks involved in investing in cryptocurrency, but if you read in well, do good research and invest in the right coins, you should be fine.
When you expect that the price of a coin will rise in the future, you’re probably not the only one. If there is confidence among a large group of investors and the prices actually go up, you speak of a bull market.
The term bull market refers to a positive trend in the prices of a market. It is broadly used not only in the cryptocurrency space but also in the traditional markets. In short, a bull market concerns to a strong market uptrend that presents meaningful rising prices over a relatively short period of time. When compared to traditional markets, cryptocurrency markets are smaller and consequently more volatile.
