Bitcoin is a ‘coin gateway’ for many investors;  they buy Bitcoin BTC before buying other coins.  This could be partly due to the almost universal listing on every active cryptocurrency exchange, but also due to the high profile and low volatility (which is a relative statement).  This visibility, along with Bitcoin's price and position in the crypto market, is total market dominance.
Many experts predict that Bitcoin is still a great investment that will pay off in the long term, while we can expect more of the same rollercoaster ups and downs in the short term.  Bitcoin news is an art form in itself and you need to make sure you know what comes next in terms of cryptocurrency regulations, cryptocurrency exchange news and in-depth crypto market analysis.
