In essence, bitcoin is a public ledger shared by a network of computers. To pay with or to exchange bitcoins, you send a signed message transferring ownership to a receiver’s public key. Each bitcoin is locked by a second private key. Think of a private key as a more complicated series of passwords called a “seed.” No one can access any amount of bitcoin without a private key. Obviously, it is crucial that you keep track of both the public and private keys, and do not share those keys except with a person you trust as your backup. If you lose your keys, you lose your bitcoin.
Blockchain is the revolutionary record-keeping technology that is the backbone of bitcoin. No single person or group has control of the currency; all users are in control collectively. The larger the bitcoin network gets, the more secure it gets. The computer hubs (called nodes) all over the world are all continually fact-checking each other’s ledgers. Each translation is scrutinized. When bitcoin is exchanged, it’s as if millions of tellers are simultaneously confirming the validity of the translation.

How much is bitcoin worth?
How much is one bitcoin worth? Well, it depends on the day. Bitcoin has value because enough people believe bitcoin has value. That may be no different than gold. Gold is really just a shiny rock; but because it was “decided” centuries ago that gold was desirable (and scarce), it is considered a store of value. It became a currency and also a store of wealth, and a portfolio asset in modern times.
While no one knows with any certainty how much gold might be discovered, the algorithm for bitcoin release is capped at 21 million coins. To date, just over 18.5 million bitcoins have been created, and there are almost 2.4 million coins left to be released. Currently, 900 coins are released each day, and the last bitcoins will be released around 2040. Bitcoin “miners” (a.k.a. programmers) are rewarded with the new bitcoins, in payment for their verifications of the transaction on the blockchain.
It is the scarcity of bitcoin, and its finite quantity, that offer the greatest appeal to those who reject or question the value of fiat currencies such as the US dollar, the euro or the Canadian dollar. Certainly, bitcoin, as well as fiat currencies, are created “out of thin air.” But while central banks can create as much new currency as they see fit, there is a hard limit to the amount of bitcoin. That’s why those who favour bitcoin often call it “the hardest currency on earth.”
On the other side of the ledger, critics will offer that bitcoin is worthless because it is created out of thin air, and only backed by those who accept and exchange bitcoin, and assign value. In contrast, fiat currencies are backed by the wealth creation and taxing powers of each nation.
How is bitcoin mined, exactly?
Programmers (bitcoin miners) have to locate the new coins and then perform a series of complex mathematical equations in order to unlock the new coins. These miners collectively are also required to confirm ongoing bitcoin transitions verifying the details. As noted above, millions of digital eyeballs are on each transaction. But in the end, only one miner or miner group (called a “node”) will be rewarded with the new issue of bitcoins.
The successful miner “walks away” with the new coins, and the group of confirmed and verified bitcoin transactions (the “block”) is added to the existing record (“chain”) of transitions. That is how we get to the name and technology known as the “blockchain.”
Informative thank you – I have been looking at the 3iq fund bit then it made the sharp increase before I could act – so monitoring for now.
Is this Worth investing into in February 2021??

Thanks for an excellent article. Can bitcoin be purchased in Corp or non-registered account ?
very interesting
If you do decide to invest in this space you need to look at your entire portfolio and decide what % of your money you are inclined to do so with. I am not a professional advisor but having been invested for many many years in the markets taking an allocation of 5% should by the most for this sector. It is also very volatile so losing your money is a higher possibility than many other sectors of our markets.
I understand that on Thursday, Feb 18 this week Canada will start trading the world’s first Bitcoin ETF which I would think must be a very easy (and safe?) way to trade it.
Hi Blair Rogerson and other readers. Apologies I was not tracking this for comments. It is such a volatile asset that one might consider building a position over time. Obviously from end of January, bitcoin has had another great run.
We have to be prepared for incredible volatility on both sides.
We might build positions, and then have a rebalancing (exit) strategy as well to take advantage of explosive gains to the upside.

Thank you for explaining your are right I am over 55. This new asset class was totally not understood.
Thank you. P
Hi,
I have a couple of questions, I have some graphics cards that will work for mining BitCoin, my questions are:
1) If I earn some bitcoins how do I value them for Canada Revenue?
2) After I own them I assume any gains or losses are probably treated as Capital Gains?
3) I’m retired & would like to keep this separate from my various other income sources, so I’m thinking of starting a Canadian numbered company & if I leave the bitcoin in the company(pay any taxes there) & does it only get added to my personal income when taking a dividend or some other payment from the company?

I made some money on Bitcoin with GBTC. However, I have changed my opinion on Bitcoin and cryptos. I think they have no future when countries ban them and create their own digital currencies. With the recent Colonial Pipeline hack, I’m pretty sure the US is going to do something about cryptos.
In what sane universe can a 27 year old (Ethereum) create value out of thin air and attain a net worth of $20 billion?
Cryptos = Tulipmania.
