In finance, you can assess how crypto currencies are doing by comparing market capitalization between them. Bitcoin dominance is the value of all Bitcoins added together divided by the total value of all other crypto coins. Let's see why this is an important percentage.
In 2009, Bitcoin was the only crypto currency and Bitcoins dominance was obviously 100%. That changed with the launch of Ethereum in 2015 and especially when its price rocketed up in 2017. Since then, Bitcoin's dominance has hovered around 50% See chart below. At this writing (September 2022), Bitcoin makes up 40% of the total market value of the crypto market.
Of course, you can create a dominance graph of each crypto currency. If you were to make the chart for Ethereum, you would see that Ethereum dominance is now about 20%. This means that Bitcoin and Ethereum together make up over 60% of the total crypto market.
Bitcoin dominance is a percentage. As such, it is a measure of Bitcoin's relative importance. Why is such a percentage useful to include?
In short, the percentage of dominance chart allows with to spot trends. It is a clear signal.
Bitcoin dominance, of course, is a measure of how important the market considers Bitcoin relative to altcoins. This is more than a number: it has traditionally also been a measure of the state of the crypto market as a whole:
Immediately a side note to the above two rules of thumb. The share of stablecoins in the crypto market has grown rapidly since 2020: from less than 3% to a peak of 16% in June 2022. Because dollar stablecoins (such as USDC and USDT) are the preferred refuge of crypto investors, Bitcoin dominance rises less in times of uncertainty than it used to.
Therefore Bitcoin dominance is unlikely to return to pre-2017 highs: Bitcoin has been overtaken on the left by more speculative altcoins as well as on the right by more conservative stablecoins. And that's fine: it shows that the crypto market is diverse. However, it does mean that BTC dominance is now a less good measure of how much risk investors are willing to take. Stablecoin dominance is now a better measure of that.
The term altcoin season or alt season is used for the period when altcoins outperform Bitcoin. A bull market often begins with Bitcoin's rise in price and dominance. What traders try to time is the moment when the dominance begins to decline. That is the beginning of alt season.
In the chart at the beginning of this article, you can see that Bitcoin dominance rises hard in the last quarter of 2020. That was when the crypto bull market really took off. Around the turn of 2020/2021, Bitcoin dominance dropped sharply. It was the beginning of alt season.
It is noteworthy that Bitcoin dominance has not rebounded (yet) in the bear market of 2022. Partly, as mentioned above, this has to do with the flight into stablecoins, a larger market today than in the past. Partly it may have to do - but this is far from certain - with Ethereum, which is increasingly stepping out of the shadow of big brother Bitcoin. For seven years now, Ethereum has proven itself to be a solid technology with a growing number of applications. It is being seen less and less as a high-risk investment - and thus could lose less dominance in bear markets. That keeps Bitcoin's rise in dominance in bear markets in check.

What better use for blockchain technology than supply chains? Both are chains, right? Maybe that’s what the VeChain team thought to themselves when they launched in 2015. All jokes aside, the company has made strides in creating a platform for the currently siloed space of supply chain data for businesses.

On the surface, Nostr is much like a stripped-down version of Twitter. But just like Bitcoin works in fundamentally different ways from traditional money, under the hood Nostr works very different from conventional social media. In Nostr, YOU own your account. Also, Nostr lends itself to integration with wallet software and Bitcoin's Lightning network. Let's dive in and experiment.

Since the birth of Bitcoin people have been worried about improving decryption technology one day becoming capable of breaking the encryption. A recent paper by Chinese researchers claiming a quantum computation breakthrough - which most consider a hoax - adds fuel to the fire. How likely a candidate is quantum computing to ever break Bitcoin's encryption?
