So what’s the actual difference between Bitcoin and Altcoins?
- Bitcoin has long been the king of the cryptocurrency market.
- New coins and tokens have shaken up the status quo with unique use cases and innovations.
- Bitcoin has responded with its own improvements, leading to a healthier market.
When it comes to cryptocurrency, Bitcoin has long been the king of the hill thanks to its status as the founder of the young industry and its first-mover appeal. A decade later, the original cryptocurrency is still the most valuable one on the market, at one point even reaching as high as $20,000 for a single Bitcoin. Today it is far from alone in the field. As blockchain (the technology that cryptocurrency is based on) evolved, so did the number of coins available, and the things these new coins' blockchains could accomplish.
These new cryptocurrencies dubbed "altcoins" use the same decentralized concept as Bitcoin but take things a step further with unique features. Ethereum, the second most popular cryptocurrency, introduced the idea of "smart contracts", code that can automatically execute agreements between two parties using blockchain technology. This opened the floodgates for the development of new use cases and applications for crypto.
More importantly, Altcoins have improved on overall functionality, processing transactions faster than bitcoin, and generally scaling to meet expanding demand for their services. As the market for Altcoins continues to expand, it's easy to wonder if Bitcoin's lead will end soon, or if it will be able to keep up with the new generation of cryptocurrencies.
A new take on old problems
Bitcoin was originally developed as an idea for alternative, decentralized digital currency that could eventually replace fiat money like the dollar and the euro. As such, it was built for simple transactions and uses a peer-to-peer consensus mechanism to power a network to collectively verify transactions, adding them to the "chain", which is comprised of a string of transactions in batches called blocks. As a payment mechanism, bitcoin still falls far short of methods like credit cards and even other digital payment tools. Moreover, verifying ("mining") transactions is resource intensive and expensive.
Newer coins use different mechanisms to reduce both the cost and complexity of mining and can process many more transactions per second than bitcoin's paltry seven. Additionally, some of these new cryptocurrencies use technology such as smart contracts, which let them build innovative apps directly on the blockchain.
Coins like Ripple and Dash, for example offer a fresh take on the transactability and speed of payments. Ripple is designed to facilitate centralized cross-border transactions between large corporations and institutions. Dash claims to have transaction speeds as fast as 1 second per transaction, focuses on superior security, and an easy ecosystem for individuals to manage their money.
In its original state, Bitcoin simply can't compete with these newer, more focused coins. Bitcoin was built as a catch-all currency, and its creator likely didn't envision the multiple use cases of blockchain technology. This imbalance has led pundits and industry veterans to repeatedly claim that Bitcoin is on its way out.
Old coins can learn new tricks
It seems that rumors of Bitcoin's end were greatly exaggerated and instead of fading into obsolescence, it's evolved to catch up to the Altcoin market, expanding its usability. In fact, Bitcoin still has the larger user base, which comes with mainstream appeal and substantial interest from developers. Now, it's fighting off newcomers by adding new tools and functionality over time.
Instead of building the next Bitcoin, many projects have chosen instead to build on the existing Bitcoin architecture, adding new features that make the currency more usable in various situations. RSK, for instance, gives users smart contract capabilities for Bitcoin, opening the doors for app development. Whereas this was once Ethereum's major draw, Bitcoin is now encroaching on that territory with expanded functionality from RSK's platform.
Similarly, tools like the Lightning network let users take their Bitcoin transactions off chain, taking the burden off the main Bitcoin blockchain and speeding up the pace at which peripheral transactions can be verified. These solutions don't change Bitcoin's original design but make it more competitive against younger and newer coins looking to claim the spotlight. In fact, improving these issues will only expand Bitcoin's usability and mainstream popularity.
A flourishing ecosystem
Although in theory Bitcoin could eventually be capable of doing everything Altcoins can, the reality is that it still benefits from the competition. As yet, blockchain is a young technology which requires a thriving ecosystem to truly develop and become valuable to society. Moreover, Bitcoin could do well to avoid feature creep and lose its value. The beauty of blockchain is that it allows for cryptocurrencies to be used for much more than just paying for things.
Tools like Golem, a blockchain-powered crowdsourced super-computer, or Fishcoin, which tracks fish and seafood from the sea to millions of kitchens for ethical fishing and sustainable operations, take the concept of blockchain in experimental new directions. Bitcoin is designed to be a digital currency, and it's only getting better at it. However, in a world where data is transactional by design, nearly any idea will inevitably be revolutionized by transplanting it into a decentralized ecosystem—and Bitcoin is the root of it all.

A new study finds that dogs fed fresh human-grade food don't need to eat—or do their business—as much.
- Most dogs eat a diet that's primarily kibble.
- When fed a fresh-food diet, however, they don't need to consume as much.
- Dogs on fresh-food diets have healthier gut biomes.
Four diets were tested<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTU5ODI1MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1NjY0NjIxMn0._w0k-qFOC86AqmtPHJBK_i-9F5oVyVYsYtUrdvfUxWQ/img.jpg?width=980" id="1b1e4" class="rm-shortcode" data-rm-shortcode-id="87937436a81c700a8ab3b1d763354843" data-rm-shortcode-name="rebelmouse-image" data-width="1440" data-height="960" />

Swanson</a> of U of I's Department of Animal Sciences and the Division of Nutritional Sciences, was a bit surprised at how much better dogs did on people food than even refrigerated dog chow. "Based on past research we've conducted I'm not surprised with the results when feeding human-grade compared to an extruded dry diet," he <a href="https://aces.illinois.edu/news/feed-fido-fresh-human-grade-dog-food-scoop-less-poop" target="_blank">says</a>, adding, "However, I did not expect to see how well the human-grade fresh food performed, even compared to a fresh commercial processed brand."</p>

This resulted in their producing 1.5 to 2.9 times the amount of poop produced by dogs on the fresh diets.</p><p>Says Swanson, "This is consistent with a 2019 National Institute of Health study in humans that found people eating a fresh whole food diet consumed on average 500 less calories per day, and reported being more satisfied, than people eating a more processed diet."</p><p>Maybe even more interesting was the effect of fresh food on the gut biome. Though there remains much we don't yet know about microbiota, it was nonetheless the case that the microbial communities found in fresh-food poo was different.</p><p>"Because a healthy gut means a healthy mutt," says Swanson, "fecal microbial and metabolite profiles are important readouts of diet assessment. As we have shown in <a href="https://academic.oup.com/jas/article/92/9/3781/4702209#110855647" target="_blank">previous studies</a>, the fecal microbial communities of healthy dogs fed fresh diets were different than those fed kibble. These unique microbial profiles were likely due to differences in diet processing, ingredient source, and the concentration and type of dietary fibers, proteins, and fats that are known to influence what is digested by the dog and what reaches the colon for fermentation."</p>
How did kibble take over canine diets?<p>Historically, dogs ate scraps left over by humans. It has only been <a href="https://www.thefarmersdog.com/digest/the-history-of-commercial-pet-food-a-great-american-marketing-story/" target="_blank">since 1870</a>, with the arrival of the luxe Spratt's Meat Fibrine Dog Cakes—made from "the dried unsalted gelatinous parts of Prairie Beef", mmm—that commercial dog food began to take hold. Dog bone-shaped biscuits first appeared in 1907. Ken-L Ration dates from 1922. Kibble was first extruded in 1956. Pet food had become a great way to turn <a href="https://www.dogfoodadvisor.com/choosing-dog-food/animal-by-products/" target="_blank">human-food waste</a> into profit.</p><p>Commercial dog food became the norm for most household canines only after a massive marketing campaign led by a group of dog-food industry lobbyists called the Pet Food Institute in 1964. Over time, for most households, dog food was what dogs ate — what else? Human food? These days more than half of U.S. dogs are <a href="https://www.nytimes.com/2014/08/03/magazine/who-made-that-dog-biscuit.html" target="_blank">overweight or obese</a>, and certainly their diet is a factor.<span></span></p><p>We're not so special among animals after all. If something's healthy for us to eat—we're <em>not</em> looking at you, chocolate—maybe we should remember to share with our canine compatriots. Not from the table, though.</p>
What makes some people more likely to shiver than others?
Some people just aren't bothered by the cold, no matter how low the temperature dips. And the reason for this may be in a person's genes.
Eating veggies is good for you. Now we can stop debating how much we should eat.
- A massive new study confirms that five servings of fruit and veggies a day can lower the risk of death.
- The maximum benefit is found at two servings of fruit and three of veggies—anything more offers no extra benefit according to the researchers.
- Not all fruits and veggies are equal. Leafy greens are better for you than starchy corn and potatoes.
