What Is Bitcoin?

Most people think they already know the answer. It's digital money. It's decentralized. Satoshi invented it in 2009. Fine — but none of that explains why BTC swings 30% in a month, why it can drop from $69K to $16K in a year, or why it then climbs to $100K like the crash never happened. Understanding what Bitcoin is matters less for trading it than understanding how Bitcoin behaves. Those are different questions.

Here's what actually drives BTC's price: speculation, narrative cycles, and institutional flows. Not usage. Not transaction volume. The majority of BTC held today isn't being spent on coffee — it's sitting in wallets as a store of value bet. That makes it more like gold with a press release than a currency. And it means the price is almost entirely sentiment-driven, which is why technical indicators can actually work on it in a way they can't on, say, a company's stock.

The Volatility Profile

BTC is one of the most volatile tradeable assets on the planet. Not startup-stock volatile. Genuinely wild. In 2022 alone, it dropped from $47K in January to $16K in November — a 66% drawdown over ten months. Then it was back above $69K by late 2024.

Stocks don't do that. The S&P 500's worst single year in recent memory was -19.4% in 2022. BTC dropped 64% that same year.

This volatility is structural. BTC has no earnings, no dividends, no cash flow to anchor its price. It's priced entirely on what the next buyer is willing to pay. During bull markets, that number can climb absurdly fast. During bear markets, it can fall through the floor.

For someone using a signal-based strategy, this cuts both ways. The wild swings create big signal opportunities — MACD is designed to detect exactly this kind of momentum acceleration. But the reversals are also violent. A bullish trend can evaporate in days.

Why BTC Trends (And Why Those Trends Break Violently)

BTC is a momentum asset. When it moves, it tends to move in a direction for a while. Bull runs last months, sometimes over a year. Bear markets are similarly persistent. This is what makes MACD — which measures momentum — a reasonable fit for BTC.

But BTC also has a habit of violent trend reversals that catch momentum indicators off guard. The 2021 bull run peaked at $69K. Within a year, it was below $16K. MACD trends that looked strong in early 2022 turned negative fast.

This is where our strategy is honest about its limits. BTC trends tend to be momentum-driven, which is exactly what MACD is designed to detect — but the trends also reverse violently, which is why our signals underperform in choppy quarters. In the five years we've backtested, our BTC signals beat buy-and-hold in exactly 50% of quarters. Roughly a coin flip. The value isn't in most quarters — it's in the crash quarters, where being out of the market early makes a decisive difference.

What Has Historically Driven BTC's Price

Halving cycles. Every four years, the amount of new BTC mined per block gets cut in half. Historically, these halvings have coincided with major bull runs — though whether that's causal or coincidental is genuinely debated. The 2020 halving was followed by a run to $69K. The 2024 halving was followed by a run past $100K. The pattern has held so far. Whether it continues is unknown.

Macro correlation. Since 2020, BTC has increasingly traded like a risk asset. When the Fed raises rates aggressively (as it did in 2022), BTC sells off alongside tech stocks. When liquidity expands, BTC rallies. This correlation isn't fixed — it's broken down at times — but it's real enough that watching the macro environment matters for understanding BTC's medium-term direction.

Institutional flows. The arrival of spot Bitcoin ETFs in January 2024 changed the market structure. BlackRock's IBIT ETF alone accumulated over $50 billion in assets in its first year. These flows don't operate the same way retail buyers do. They're larger, slower, and more correlated with traditional finance. That's probably one reason BTC's 2024 rally felt different from 2021 — bigger institutional backing, less retail mania.

These factors don't give you a trading edge by themselves. But they explain why BTC moves the way it does — and why understanding context matters when you're interpreting signals.

BTC is a sentiment-driven momentum asset with structural volatility — that's what makes it tractable for momentum indicators like MACD, and it's also why those signals can fail spectacularly when the narrative flips.
