Bitcoin’s first mover advantage, popularity, and network effect has cemented it as the most popular cryptocurrency with the largest market cap. Rivals like Litecoin may have numerous technical advantages over Bitcoin’s algorithm (see more about that here), but they only hold a fraction of Bitcoin’s market cap and their dwindling communities largely consist of loyalists, speculators, and antagonistic anti-Bitcoin buyers. 

Although there are no guarantees that Bitcoin will continue to rise in value, the future does look bright for this exciting cryptocurrency. Unlike leveraged instruments, you can rest assured that your exposure to Bitcoin is limited to what you pay for it. (This does not apply to Bitcoin or other cryptocurrency derivatives that may be leveraged or shorted).
Our second assumption is that the supply of bitcoin will approach 21 million as specified in the current protocol.  To give some context, the current supply of bitcoin is around 17 million, the rate at which bitcoin is released decreases by half roughly every four years, and the supply should get past 19 million in the year 2022.  The key part of this assumption is that the protocol will not be changed.  Note that changing the protocol would require the concurrence of a majority of the computing power engaged in bitcoin mining.

Speculation drives numbers. Many Bitcoin users are holding onto their bitcoins in hopes of selling them off for an enormous profit one day. With news articles portraying Bitcoin millionaires as lucky kids who got in early, you can’t really blame them. For example, if you had spent your $5 latte money on 2,000 bitcoins one morning in 2010, they would be worth about $5.4 million today. Makes you really wish you’d managed your Starbucks budget better, doesn’t it?


It’s decentralized and brings power back to the people. Launched just a year after the 2008 financial crises, Bitcoin has attracted many people who see the current financial system as unsustainable. This factor has won the hearts of those who view politicians and government with suspicion. It’s no surprise there is a huge community of ideologists actively building, buying, and working in the cryptocurrency world.
"While crypto markets have seen rapid growth, such trading platforms don’t seem to be well-enough prepared in terms of security," said Hong Seong-ki, head of the country's cryptocurrency response team South Services Commission. "We’re trying to legislate the most urgent and important things first, aiming for money-laundering prevention and investor protection. The bill should be passed as soon as possible."

Because of bitcoin's decentralized nature and its trading on online exchanges located in many countries, regulation of bitcoin has been difficult. However, the use of bitcoin can be criminalized, and shutting down exchanges and the peer-to-peer economy in a given country would constitute a de facto ban.[164] The legal status of bitcoin varies substantially from country to country and is still undefined or changing in many of them. Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems.[165]
In 2014 prices started at $770 and fell to $314 for the year.[31] In February 2014 the Mt. Gox exchange, the largest bitcoin exchange at the time, said that 850,000 bitcoins had been stolen from its customers, amounting to almost $500 million. Bitcoin's price fell by almost half, from $867 to $439 (a 49% drop). Prices remained low until late 2016.[citation needed]
In January 2015 Coinbase raised 75 million USD as part of a Series C funding round, smashing the previous record for a bitcoin company.[109] Less than one year after the collapse of Mt. Gox, United Kingdom-based exchange Bitstamp announced that their exchange would be taken offline while they investigate a hack which resulted in about 19,000 bitcoins (equivalent to roughly US$5 million at that time) being stolen from their hot wallet.[110] The exchange remained offline for several days amid speculation that customers had lost their funds. Bitstamp resumed trading on 9 January after increasing security measures and assuring customers that their account balances would not be impacted.[111]
Additionally, FinCEN claimed regulation over American entities that manage bitcoins in a payment processor setting or as an exchanger: "In addition, a person is an exchanger and a money transmitter if the person accepts such de-centralized convertible virtual currency from one person and transmits it to another person as part of the acceptance and transfer of currency, funds, or other value that substitutes for currency."[60][61]
Bitcoin is a type of cryptocurrency: Balances are kept using public and private "keys," which are long strings of numbers and letters linked through the mathematical encryption algorithm that was used to create them. The public key (comparable to a bank account number) serves as the address which is published to the world and to which others may send bitcoins. The private key (comparable to an ATM PIN) is meant to be a guarded secret, and only used to authorize Bitcoin transmissions.

“So if you look at a $100 billion market cap today, now last week it might have been more like 200, so it’s actually a buying opportunity, we think that there’s a potential appreciation of 30 to 40 times because you look at the gold market today, it’s a $7 trillion market. And so a lot of people are starting to se that, they recognize the store of value properties.”
On 6 August 2010, a major vulnerability in the bitcoin protocol was spotted. Transactions weren't properly verified before they were included in the transaction log or blockchain, which let users bypass bitcoin's economic restrictions and create an indefinite number of bitcoins.[25][26] On 15 August, the vulnerability was exploited; over 184 billion bitcoins were generated in a transaction, and sent to two addresses on the network. Within hours, the transaction was spotted and erased from the transaction log after the bug was fixed and the network forked to an updated version of the bitcoin protocol.[27] This was the only major security flaw found and exploited in bitcoin's history.[25][26]
That low point in unique addresses is a point where Bitcoin was hovering around $6,900 USD back around April 11, 2018. Using the seven-day average of the number of unique addresses (which smoothes out low points caused by low volume on the weekends), you can see that growth has returned since April to this underlying fundamental. The price today is lower, but the number of users appears to be growing again, and this time the network can support more transactions than before due to the rise of Segwit Adoption. If I had to guess I would say Bitcoin could now handle 50% to 100% more transactions per second than when we had the last peak in December/January.

If fewer people begin to accept Bitcoin as a currency, these digital units may lose value and could become worthless. There is already plenty of competition, and though Bitcoin has a huge lead over the other 100-odd digital currencies that have sprung up, thanks to its brand recognition and venture capital money, a technological break-through in the form of a better virtual coin is always a threat.
Though Bitcoin was not designed as a normal equity investment (no shares have been issued), some speculative investors were drawn to the digital money after it appreciated rapidly in May 2011 and again in November 2013. Thus, many people purchase bitcoin for its investment value rather than as a medium of exchange. But their lack of guaranteed value and digital nature means the purchase and use of bitcoins carries several inherent risks. Many investor alerts have been issued by the Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), the Consumer Financial Protection Bureau (CFPB), and other agencies.
Bitcoin is an increasingly popular cryptocurrency that utilizes blockchain technology to facilitate transactions. Basically, a user obtains a Bitcoin wallet that can be used for storing bitcoins and both sending and receiving of payments. The blockchain technology used by Bitcoin is really just a shared public ledger that is used by the entire public network. The technology used is secured through cryptography, a branch of mathematics that provides a highly secure means of facilitating and recording transactions on the network.

The successful miner finding the new block is rewarded with newly created bitcoins and transaction fees.[83] As of 9 July 2016,[84] the reward amounted to 12.5 newly created bitcoins per block added to the blockchain. To claim the reward, a special transaction called a coinbase is included with the processed payments.[3]:ch. 8 All bitcoins in existence have been created in such coinbase transactions. The bitcoin protocol specifies that the reward for adding a block will be halved every 210,000 blocks (approximately every four years). Eventually, the reward will decrease to zero, and the limit of 21 million bitcoins[f] will be reached c. 2140; the record keeping will then be rewarded solely by transaction fees.[85]
No one knows. Not conclusively, at any rate. Satoshi Nakamoto is the name associated with the person or group of people who released the original Bitcoin white paper in 2008 and worked on the original Bitcoin software that was released in 2009. The Bitcoin protocol requires users to enter a birthday upon signup, and we know that an individual named Satoshi Nakamoto registered and put down April 5 as a birth date. And that's about it.
More recently, at a congressional hearing on Capitol Hill, global economist and New York University professor Nouriel Roubini said, "Crypto is the mother or father of all scams and bubbles." He called out "swindlers" who tapped into investors' fear of missing out and took them for a ride with "crappy assets that went into a bust and crash — in a matter of months — like you have not seen in any history of financial bubbles."
