স্বপ্নের শঙ্খচিল বলেছেন: Welcome to Bitcoin Basics Lesson 3: Bitcoin Exchange Rates

In Lesson 2, you learned that bitcoin is pseudonymous rather than anonymous and that you can make use of a wallet to protect and access your money. You also learned that bitcoins are stored in a public ledger called the blockchain, and that you can buy bitcoins on exchanges, with a credit card, or by using ATMs. We explored how bitcoin isn’t printed like regular money; it’s discovered, or ’mined’, by a network of computers worldwide.

In Lesson 3 you will learn:

Bitcoin has a value set by the laws of supply and demand
Because of its current adoption phase and limited distribution, exchange rates are often influenced by news
Bitcoin has a fixed supply that is limited to 21 million units total


Bitcoin's Value
How is the value of bitcoin determined? Well, all currencies and commodities have an exchange value, agreed upon by the seller and buyer. Bitcoin is a currency because it is a limited medium which people have agreed possesses value. This agreement is no different from ancient merchants who at one time did the same thing with materials such as seashells, precious stones, gold, or silver. The difference between bitcoin pricing and the pricing of paper money is that bitcoin’s value is set solely by the supply and demand within the community. There is no governing body like a central bank e.g. The Federal Reserve to influence or control the flow of money. Given that bitcoin is in its infancy, and has yet to fully find its identity and function, the price is easily influenced by news and rumours.

Large markets like the EU, China, Japan or the US may announce new bitcoin regulations, either favourable or restrictive to bitcoin’s growth, causing the price to rise or fall respectively. Other factors that can influence the value of bitcoin are internal issues. Examples of this include miners’ conferences or a meeting to decide changes to the Bitcoin protocol. The price may sometimes dip if an agreement on a subject cannot be reached, or seems to be too far off.

Supply & Demand
The supply of bitcoin is limited to 21 million units. This was set according to the initial design of the Bitcoin software, and this limitation is fixed into the bitcoin algorithm. As more and more people come to use Bitcoin, the increased demand combined with the fixed supply will force the price to go up. Because the number of people using Bitcoin in the world is still relatively small, the price of Bitcoin (in comparison to a more traditional currency) can fluctuate significantly on a daily basis. As more people continue to use Bitcoin, the value of the network increases. In early 2011 one bitcoin was worth less than one USD, but in early 2017 one bitcoin was worth more than one thousand USD. If Bitcoin continues to grow, a single bitcoin could be worth more than a hundred thousand dollars.

Due to the limited number of bitcoins in circulation, and the fact that new bitcoins are created at a predictable and decreasing rate (currently 12.5 bitcoins on average every 10 minutes), the demand for bitcoin must follow the supply increase to keep the price stable.

Like any other money, the value of Bitcoin will grow with more user adoption and trust. This can be measured by its growing base of users, merchants, and startups. As with all currencies, bitcoin's value is determined directly by people willing to accept them as payment.

This ends today’s lecture. Now you know that bitcoin has a value set by the laws of supply and demand, and because of its relatively early phase of adoption and limited distribution, prices are easily influenced by news. You have also learned that the total supply of bitcoin is limited to 21 million units.

Tomorrow you will learn more about how bitcoin wallets work.

স্বপ্নের শঙ্খচিল বলেছেন: Bitcoin has a maximum supply of 21 million coins.

However, there are fractional units of bitcoin and bitcoin cash.

These can be useful for expressing small denominations of the cryptocurrency, such as when making micro transactions. (As one example, think bitcoin faucets where a person can regularly earn small amounts of bitcoin.)

Let’s take a look at how small units of bitcoin are converted to U.S. dollars (at a BTC price of $10,000):

A milli-bitcoin (mBTC) represents 1 / 1,000th of a bitcoin or $10 USD.

A micro-bitcoin, or bits (μBTC) represents 1 / 1,000,000th of a bitcoin or $0.01 USD (one penny).

A satoshi is one hundred millionth of a single bitcoin or $0.0001 USD. It’s the smallest unit of bitcoin that can be recorded on the block-chain.

You can convert bitcoin and bitcoin cash into these micro denominations using Bitcoin.com’s Price Converter tool. (It converts price for most fiat currencies.)

স্বপ্নের শঙ্খচিল বলেছেন: Bitcoin is the world’s most popular cryptocurrency but not all newbies know everything there is to know about BTC. So we listed 12 interesting facts about bitcoin that you can share with friends at your next cocktail party.

1. Satoshi Who?
An entity by the name of Satoshi Nakamoto published the designs of bitcoin in the whitepaper “Bitcoin: A Peer-to-Peer Electronic Cash System.” However, no one knows exactly who Satoshi is, and whether or not he/she is an individual or group, or perhaps government agency. To this day, Satoshi’s identity remains a mystery.

2. Not So New
Media outlets are presenting cryptocurrencies as a new phenomenon, but bitcoin has actually been around for a decade. Satoshi Nakamoto released his groundbreaking whitepaper in the midst of the U.S. financial crisis in 2008. A decade is quite some time.

3. Expensive Pizza
The first transaction took place in 2009 when Hal Finney bought pizza for 10,000 bitcoins. That’s equivalent to $110,000,000 USD at $11,000 per BTC. The real question is: How many slices did that pizza come with?

4. Limited Supply
The last remaining bitcoins will be mined in 2140. And only a maximum number of 21 million bitcoins can ever exist. Many people, especially skeptics, are undoubtedly regretting not buying bitcoin sooner.

5. Legal Money
Bitcoin is a legally accepted means of payment in many countries but most notably in Japan. There are 200,000 to 250,000 transactions per day.

6. Network of Supercomputers
It’s virtually impossible to hack the bitcoin network as miners collectively possess more computing power than any of the world’s most powerful supercomputers. Experts estimate it to reach over 2 million petaflops/s.

7. Crypto Auctions
The U.S. government is the biggest auctioneer of bitcoin. And the FBI manages one of the world’s biggest wallets with as much as $120 million worth of BTC. In 2013, the FBI seized 144,000 bitcoins connected to Silk Road.

8. Concentrated Wealth
While blockchain technology makes bitcoin a decentralized cryptocurrency, it’s estimated that less than a thousand people own 40% of the bitcoin market.

9. Brand Awareness
In December 2013, only 4 in 10 Americans were aware of bitcoin. By September 2017, that figure had grown to nearly 80%.

10. To The Moon
A lot of videos and articles claim that bitcoin will eventually reach a $1 million valuation per coin. While others claim that BTC could be the biggest bubble since tulip mania in the Netherlands some 400 years ago. Use your own judgment.

11. “We Accept Bitcoin”
Over 100,000 merchants worldwide accept bitcoin as a payment method. But that figure also includes large companies such as Microsoft, Intuit, DISH Network and Expedia.

12. Buy Real Estate
Bitcoin holders have bought real estate with BTC. One mansion in Miami, Florida sold for 1,600 BTC. Other places where investors have used bitcoin to purchase real estate include Dubai, New York City, Lake Tahoe (California) and Bali (Indonesia). At least they didn’t use 10,000 bitcoins to buy a single pizza.
