because bitcoin sells more money than other coins so its price moves faster because they can be certain that when they invest in it now and sell when its price rises they will earn a lot of money.

If we compare other altcoins against Bitcoin, we'll notice that the latter has much wider acceptance within the mainstream world. The reasons for this are obvious as Bitcoin is the world's largest cryptocurrency by market cap. Being the first original cryptocurrency in existence, it has managed to obtain a recognized branding that anyone trusts worldwide. Despite other altcoins being superior than Bitcoin in terms of transaction capacity with some additional functionalities, they're lacking the trust necessary to move on within the mainstream world. With lesser liquidity than Bitcoin and a lower degree of development, many people prefer to deal with the original cryptocurrency than anything else.

I believe that the current market situation is related to investors selling off their altcoins in exchange for Bitcoin. This brings up a greater level of demand for the pioneer cryptocurrency, allowing market dominance to rise like never before. Right now, dominance is rising faster than usual as people are losing interest into many altcoins being traded on the market today. Within a couple of years from now, Bitcoin would've obtained a market dominance of over 90% while altcoins become the minority. Even so, altcoins will continue to exist because they provide other features that are not available within the Bitcoin blockchain itself. With this diversity, people can choose from one crypto to another with ease. However, Bitcoin will be always be the reserve crypto of the market no matter what.

Nonetheless, Bitcoin's ever-rising market dominance shows us how powerful the cryptocurrency is within the mainstream world. Most altcoins will be seen as a gamble or a speculative instrument, while Bitcoin will be recognized by many as "digital gold". Which means that, Bitcoin will remain in its top position in market cap for a very long time. Just my thoughts

bitcoin market dominance is growing fast because the main reason is market is taking new parabolic path for gbrowth with this new cycle we will see new price growth new alltime high

Although bitcoin dominant rising fast, the price is not following to increase, and it tends to stable at a price now. Maybe the price still waits for the right moment to increase the rate so the dominant will rise more than now. Every possibility can happen later, and we could only predict, wait, and see, while we can use this time to buy more bitcoin. Meanwhile, the price itself can increase in anytime without we know the reason behind that, but I am sure that many people wait for the price to reach the highest rate again.

From a technical point of view and at the negotiation level, Bitcoin can come from a somewhat extensive accumulation stage, which means that the Altcoins have suffered great falls due to their dependence, there is currently a lot of prominence in the world, for economic problems in nations that have boosted the demand for Bitcoin.

Many analysts have confirmed the change in tendency, to bullish, although some still think that the bears will arrive, when observing the Bitcoin chart, according to Wyckoff's theory we are starting the bullish trend phase, and before that some falls and corrections occur, It is normal, the fight between bulls and bears, but given the time that Bitcoin movements have taken place, the increase in price is expected.

People worldwide are beginning to enter the Bitcoin market, they find it much more attractive to understand Bitcoin and its technology because it is the currency with more value and the most coveted than the Altcoins, some alarms that have been given so much in Argentina, Brasil, Like other countries, when accepting the negotiations with Bitcoin, it has aroused the interest of acquiring to hold, because they should know that its maximum value was for the $ 20k and that according to the news many high prices are predicted, which brings as a benefit that the demand increases .

Bitcoin’s (BTC) parabolic advance over $12,000 has taken its market dominance above 60% for the first time since April 2017, data from CoinMarketCap

Following its rapid appreciation in recent days, the bitcoin price reached levels not seen since immediately after the end of its 2017 bull run.

The successes have come at the expense of altcoins, which have so far failed to produce similar performance. As a result, BTC dominance of the overall cryptocurrency market cap is now 62% - more than at any time in the past two years.

Bitcoin’s market cap now stands at $226 billion out of a total crypto cap of $365 billion.

Bitcoin commentators rejoiced at the latest dominance figures, with the Twitter account known as Armin van Bitcoin adding he distrusted CoinMarketCap and that the actual number was closer to 95%.

Practical evidence proves the power and stability of Bitcoin.

Well, first of all, as you say, the evolution and popularity of bitcoin has been built stronger than ever through information and forums, that makes a lot of new investors enter the market, focusing on accumulating quite a lot of bitcoin, trends in the crowd appeared, Bitcoin continued to dominate stronger. Besides, we can see the strong impact from facebook, more precisely, it's called libra coin, a crypto platform, everyone knew more than crypto through the event, especially knowing that bitcoin was the best, all of which helped bitcoin go up to an absolute dominance.

Bitcoin has always been a leader, and mostly because it was created first. This is an advantage that no altcoin can overcome. And in fact, I do not know a single coin that would be better than bitcoin. And that's what most people think, as we can see.

Why is it concerning that altcoins aren't performing well? I think it's perfectly normal for shitcoins not being worth anything to not perform well. I do however have to point out that in dollar terms altcoins are doing fairly well. It's just their Bitcoin ratio that has dropped hard. That's what you get when you exchange your precious Bitcoins for trash.

What I find more concerning is that the same people who initially said that the dominance metric is useless, are now cheering for the dominance to be going higher and higher.

Crypto is irrational. No matter how worthless altcoins are, we'll be getting some sort of an altcoin pop at some point which will significantly decrease Bitcoin's dominance again. If enough people give up on altcoins in the coming months, the market will catch them by surprise and a massive bull run initiates due to people fomo'ing back in. It ain't done yet. The only questionable aspect is the timing.

It is because a lot of people see how Bitcoin is being adapted worldwide while it is also being used as a way to pay for any services/products they sell. This is how the blockchain technology changes the world. No one was expecting to see the price to surge up to $20k in 2017 and with the news of the upcoming halving of Bitcoin, people expect already to see a new ATH next year.
