In the realm of cryptocurrencies, Bitcoin (BTC) stands as not only the pioneer but also the most recognized among the staggering array of over 19,000 digital currencies existing today. The financial media thrives on chronicling every surge to new heights and gut-wrenching plummet, establishing Bitcoin as an integral part of the financial landscape.

Despite the sensational volatility that often garners headlines, Bitcoin may not be the optimal choice for newcomers or those seeking a stable store of value. To truly comprehend the intricacies, let’s delve deeper into the mechanics of how Bitcoin operates.

Understanding Bitcoin

At its core, Bitcoin represents a decentralized digital currency, enabling direct buying, selling, and exchanging without the need for intermediaries like banks. The mastermind behind Bitcoin, Satoshi Nakamoto, initially envisioned “an electronic payment system based on cryptographic proof instead of trust.”

Each and every Bitcoin transaction ever made is recorded on a public ledger accessible to all, rendering transactions resistant to tampering and falsification. This deliberate design choice underscores Bitcoin’s decentralized nature. Unlike traditional currencies backed by governments or institutions, Bitcoin derives its value solely from the inherent cryptographic integrity of the system.

As Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld, succinctly puts it, “The reason why it’s worth money is simply that we, as people, decided it has value—same as gold.” Since its launch in 2009, Bitcoin’s value has experienced a meteoric rise. From its humble beginnings at under $150 per coin, as of June 8, 1 BTC is valued at approximately $30,200. Given its capped supply of 21 million coins, many anticipate a continual rise in its value, particularly as more institutional investors embrace it as a digital hedge against market instability and inflation. Currently, more than 19 million coins are in circulation.

The Mechanism Behind Bitcoin

Bitcoin operates on a foundation known as a blockchain. This distributed digital ledger comprises interconnected blocks, each containing critical transaction information such as timestamps, total values, participants, and unique codes. These blocks are sequentially linked, forming a digital chain of information.

Stacey Harris, a consultant for Pelicoin, a network of cryptocurrency ATMs, clarifies, “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions.” This blockchain is decentralized, meaning no single entity wields control. Think of it like a collaborative Google Doc—open to contributions from anyone with the link. Each update improves every copy.

This seemingly editable nature is, in fact, what guarantees the security of Bitcoin. To incorporate a transaction block into the Bitcoin blockchain, a majority of Bitcoin holders must validate it. Furthermore, the unique codes used to identify users’ wallets and transactions must align with the correct encryption pattern.

These codes, composed of lengthy, random numbers, form an almost impenetrable barrier against fraudulent activity. The considerable statistical randomness embedded in these blockchain verification codes greatly diminishes the risk of counterfeit Bitcoin transactions.

Unveiling Bitcoin Mining

Bitcoin mining involves the process of appending new transactions to the Bitcoin blockchain. This is no easy task. Miners, who actively participate in this process, utilize a proof-of-work approach, employing computers in a race to solve intricate mathematical puzzles that authenticate transactions.

To incentivize miners to persistently solve these puzzles and support the network, the Bitcoin code rewards successful miners with 6.25 BTC for each newly added block—equivalent to nearly $190,000.

As Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax, underscores, “This is how new coins are created,” as recent transactions are woven into the blockchain. While early days allowed average individuals to mine Bitcoin, the increasing complexity of the puzzles, intentionally engineered over time, demands substantial computational resources today. Successful Bitcoin mining necessitates powerful computers and access to abundant, affordable electricity.

The rewards from mining have also dwindled, rendering it even more challenging to recoup the escalating costs of computation and electricity. Flori Marquez, co-founder of BlockFi, a crypto wealth management company, notes, “In 2009, when this technology first came out, every time you got a stamp, you got a much larger amount of Bitcoin than you do today.” The mounting volume of transactions implies diminishing rewards per stamp. By 2140, it is projected that all Bitcoins will be in circulation, leading miners to rely predominantly on transaction fees.

Exploring Bitcoin’s Utility

Within the United States, Bitcoin is not only viewed as an investment diversification tool alongside stocks and bonds but also a means of conducting transactions. While numerous companies like Microsoft, PayPal, and Whole Foods accept Bitcoin, smaller local vendors and online platforms also recognize the original cryptocurrency, albeit requiring some detective work.

Connecting a debit card to a crypto account facilitates Bitcoin usage similar to a credit card. This process typically involves instant conversion of Bitcoin to dollars by a financial service provider.

In countries grappling with volatile currencies, cryptocurrencies, including Bitcoin, often serve as a more stable alternative. Particularly in nations like Venezuela, Argentina, and Zimbabwe, where mounting debt erodes currency stability, Bitcoin garners significant traction.

When leveraging Bitcoin as a currency, rather than an investment, in the U.S., one must remain cognizant of potential tax implications.

Navigating Bitcoin Acquisition

Most individuals opt to acquire Bitcoin via cryptocurrency exchanges, platforms that facilitate the purchase, sale, and holding of cryptocurrencies. Setting up an exchange account mirrors the process of establishing a brokerage account. Identification verification and funding sources, such as bank accounts or debit cards, are prerequisites.

Prominent exchanges include Coinbase, Kraken, and Gemini. Additionally, online brokers like Robinhood offer Bitcoin acquisition services.

Regardless of the chosen exchange, owning a Bitcoin wallet is imperative. These wallets come in two varieties: hot wallets and cold wallets. Hot wallets, maintained online by exchanges or providers, offer convenience. Providers such as Exodus, Electrum, and Mycelium offer online wallets. Conversely, cold wallets, also known as mobile wallets, are offline devices that securely store Bitcoin, remaining disconnected from the internet. Trezor and Ledger are popular choices for mobile wallets.

Several vital considerations accompany Bitcoin purchases. While Bitcoin may be pricey, fractional purchases are feasible. Transaction fees, albeit minor percentages of transaction amounts, warrant attention, particularly for smaller acquisitions. Instantaneous gratification isn’t guaranteed; Bitcoin transactions demand verification by miners, necessitating at least 10 to 20 minutes for the purchased Bitcoin to reflect in your account.

The Investment Landscape

Similar to stocks, Bitcoin can be procured and held as an investment, even within specialized retirement accounts known as Bitcoin IRAs.

Strategies for Bitcoin investment vary widely. Some adopt a buy-and-hold approach, others target sales following price surges, while some even speculate on price drops. Bitcoin’s historical price fluctuations encompass massive swings, with 2020 alone witnessing values plummet to $5,165 and skyrocket to $28,990.

Flori Marquez provides insight: “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time.” This sentiment advocates for long-term investment. An avenue for consumers seeking Bitcoin exposure is the Grayscale Bitcoin Trust (GBTC), a Bitcoin mutual fund. However, the $50,000 minimum investment limits access for most Americans. In Canada, accessibility to diversified Bitcoin investment is expanding. Purpose Bitcoin ETF (BTCC) commenced trading in 2021 as the world’s first Bitcoin ETF. The Ontario Securities Commission also greenlit the Evolve Bitcoin ETF (EBIT). Yet, it’s essential to note that crypto-based funds carry greater risk and higher fees compared to traditionally steady index-based funds.

The Decision Dilemma

While many financial experts support clients’ cryptocurrency aspirations, recommendations hinge on clients’ inclinations. Ian Harvey, a certified financial planner (CFP) in New York City, reflects, “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college.” Given the speculative nature of cryptocurrencies, some advisors advocate allocating crypto investments as supplementary or “side” assets.

Scott Hammel, a CFP in Dallas, likens it to a “Vegas account,” best kept distinct from long-term investments. The consensus among planners is that Bitcoin, akin to an individual stock, shouldn’t dominate a portfolio. A prudent allocation ranges from 1% to 10%, particularly if a deep passion for Bitcoin exists. As Hammel quips, “If it was one stock, you would never allocate any significant portion of your portfolio to it.”


Bitcoin, the foremost cryptocurrency, operates as a decentralized digital currency underpinned by the unalterable blockchain technology. Its value emanates from collective human trust, akin to gold’s value. Bitcoin’s trajectory has been characterized by remarkable value appreciation, driven by its limited supply and growing institutional acceptance.

The blockchain’s decentralized structure ensures security through consensus-based validation, making fraudulent transactions exceedingly difficult. Bitcoin mining, a critical process, involves solving complex puzzles, although the diminishing returns pose challenges.

Bitcoin serves not only as an investment but also as an alternative currency in various global contexts. Its usage extends from major corporations to regions with unstable currencies.

While Bitcoin investment can offer substantial gains, its speculative nature demands cautious consideration. Advisors often counsel clients to treat crypto investments as supplementary assets, ensuring overall financial stability.
