Cryptocurrency

Digital assets with no central issuer

A cryptocurrency is a digital asset whose ownership is recorded on a blockchain, a shared ledger maintained by many computers around the world instead of by a bank or a government. No central authority issues the coins, no one can create more outside the rules written into the software, and ownership is proved with cryptography: whoever controls the private key controls the coins. That design is both the appeal and the catch. There is no head office to call when something goes wrong, no issuer obliged to buy the asset back, and no promise of income behind it.

Because nothing stands behind a cryptocurrency except the network itself, its price is simply whatever the next buyer will pay. That is not automatically a flaw, collectibles and gold work the same way, but it does mean the value rests on continued demand rather than on cash flows or a legal claim.

The main categories

The word covers thousands of very different projects. Most fall into a few broad groups:

• Bitcoin: the first and largest cryptocurrency, with a fixed maximum supply and a store-of-value narrative. It has its own bitcoin entry.
• Ether and smart-contract platforms: networks designed to run programs, not just record payments. Their tokens pay for computation on the network, and most newer crypto activity is built on platforms like these.
• Stablecoins: tokens engineered to hold a fixed value, usually one US dollar, covered in the stablecoin entry.
• The long tail: everything else, from serious experiments to outright promotions. Honesty requires saying it plainly: most of the thousands of coins launched over the years have lost nearly all their value or been abandoned. A coin existing is not evidence that it will last.

How the CRA taxes crypto: it is property, not money

This is the section every Canadian holder needs. The Canada Revenue Agency treats cryptocurrency as property, a commodity, not as currency. Using crypto is therefore treated like bartering with any other asset, and every disposition is a taxable event. You dispose of crypto when you:

• sell it for Canadian dollars or any other government currency;
• trade one coin for another, the event almost everyone misses. Swapping bitcoin for ether, or any coin for a stablecoin, is a sale of the first coin at its value that day, even though no dollars ever touched your account;
• spend it on goods or services, from a coffee to a car;
• give it away as a gift.

Capital gain or business income, and the records to keep

For most Canadians who buy and hold as investors, a disposition produces a capital gain or loss: proceeds minus your adjusted cost base, with only half of a gain added to taxable income. The ACB rules apply per coin: all your bitcoin is one averaged pool, all your ether another, exactly like identical shares. Someone who trades frequently, with short holding periods and a commercial pattern of activity, may instead be seen as earning business income, which is fully taxable. There is no bright line; the CRA weighs the facts and circumstances of each case, so very active traders should get advice.

The CRA expects records for every transaction: dates, the value in Canadian dollars at the time, what was exchanged for what, wallet addresses and exchange statements. Reconstructing years of trades afterward is painful, and platforms operating in Canada can be required to share client information with the CRA, so the safe assumption is that your activity is visible. Track as you go, and remember that moving coins between your own wallets is not a disposition; only a change of ownership is.

How Canadians buy it: regulated platforms

Canadians who want to own coins directly generally use crypto trading platforms that are registered with Canadian securities regulators and operate under conditions those regulators impose, such as rules about how client assets are held. Registration is meaningful, it weeds out the worst practices, but it is not a guarantee: it does not protect you from the price falling, and it does not make a platform failure impossible.

Crypto ETFs: the only way to shelter gains

Coins themselves cannot be held in registered accounts. A crypto ETF, which is a fund listed on a stock exchange that holds the coins for you, is a qualified investment, so it can sit inside a TFSA or RRSP. That makes ETFs the only practical way to shelter crypto gains from tax: inside a TFSA the gains are never taxed at all, and the record-keeping burden disappears because there are no dispositions to report. The trade-offs are management fees, no ability to move or spend the coins, and trust in the fund manager to custody them properly.

Self-custody: your keys, your responsibility

Holding coins in your own wallet means no platform can freeze or lose them, and it is the arrangement the technology was designed for. It also means the private key is everything: lose it and the coins are gone permanently, send funds to a wrong address and no one can reverse it. And be clear-eyed about protection: nothing anywhere in crypto is covered by [CDIC](/dictionary/cdic) deposit insurance or by [CIPF](/dictionary/cipf). Not coins on a platform, not coins in your wallet. Those safety nets exist for bank deposits and investment dealer accounts, and crypto sits outside both.

The risks, plainly

Crypto prices show extreme volatility: drops of half or more within a year have happened repeatedly, across cycles. Platforms have failed with client assets on them. Keys get lost. And the space is dense with scams, from fake investment sites to impersonation and "recovery" frauds that target previous victims. None of this means no one should ever hold crypto; it means position sizing does the heavy lifting. The widely repeated rule of thumb is honest: hold only what you could afford to lose entirely, keep it a small slice of a diversified picture, and treat any promise of guaranteed returns as the scam it almost certainly is.
