The importance of the dominant bitcoin in the cryptocurrency market
The dominance of Bitcoin (BTC) in the cryptocurrency market is very important and can be understood in several ways. This report shows how powerful and dominant Bitcoin is compared to other cryptocurrencies and offers indications about market trends. If the dominance of Bitcoin is high, it means that Bitcoin is the strongest cryptocurrency in the market.
Bitcoin dominance is one of the most important indicators to understand if the market is in a Bull Market or Low. This helps investors and traders to better understand cycles and create the right strategies.
-
During growth periods (Bull): Other cryptocurrencies (Altcoins) usually grow faster than Bitcoin, and the dominance of Bitcoin decreases.
-
During periods of decrease (bear): Bitcoin dominance increases, because people prefer bitcoin, considering it more safely.
This parameter helps investors to see in which direction the market goes and make better decisions.
Attention !! : If the dominant bitcoin is over 50% does not mean that the price of a BTC will increase, it is just a parameter !!
The impact of the dominant bitcoin for the feeling of investors
A BTC dominance growth usually indicates that the market is more defensive and more cautious about the other cryptocurrencies (Ethereum, Ripple, Shiba Inu). In such periods, investors take less risks when it comes to investments in the rest of cryptocurrencies and are more likely to invest in Bitcoin because they have a lower risk. On the other hand, a decrease in the dominant bitcoin can be considered as a period when the appetite for investments in the other cryptocurrencies increases. In these periods, we see how the market becomes much more volatile and some cryptocurrencies have a spectacular growth in a low temporal space.
The relationship between the other cryptocurrencies and the dominant bitcoin
When the dominance BTC usually increases the price and dominance of the other cryptocurrencies (also called altcoins) decreases or remains constant. And when the dominance of bitcoin decreases, then the other cryptocurrencies accumulate capitalization and their price increases. However, this is not a general rule and it is not a tip for investing, in the situation where you see that this happens.
