The Risk Specific to This Asset

Cryptocurrency investments involve significant volatility, evolving regulation, and custody risk. Understand what you are buying before sizing a position.

Risks Common to Every Crypto Asset

• Custody: losing a private key loses the asset permanently, with no recovery process
• Regulation: treatment varies by jurisdiction and changes with little notice
• Counterparty: an exchange balance is a claim on the exchange, not an asset you hold
• Volatility: 50%+ drawdowns are ordinary rather than exceptional in this asset class

What Determines Mining Profitability

Four variables decide whether a rig makes money, and only one of them is under your control.

Variable	Direction	Controllable
Coin price	Higher is better	No
Network difficulty	Rises over time, cutting your share	No
Block reward	Halves on schedule	No
Electricity cost	The whole game	Partly

Difficulty adjusts to keep block time constant, so as more hashrate joins, your share of the reward falls even though your hardware has not changed. A rig that breaks even today is usually unprofitable within a year on difficulty alone.

Electricity is where mining is won or lost. At $0.05/kWh a 3,000 W rig costs $108 a month; at $0.20/kWh the same rig costs $432. That difference exceeds most rigs' gross revenue, which is why industrial mining concentrates in a handful of cheap-power regions.

Bitcoin halvings cut the block reward by 50% roughly every four years. Any profitability projection that spans a halving needs to model it, or it is fiction after that date.

Costs That Turn a Gain Into a Loss

Cost	Typical	When it applies
Exchange fee	0.1–1.5%	Both on buy and on sell
Spread	0.05–1%	The gap between quote and fill
Network fee	$0.01–$50	Per on-chain transaction
Withdrawal fee	Fixed per asset	Moving off the exchange
Conversion	0.5–2%	Fiat in and out

A 1% fee on each side of a trade is 2% of the position, which on a 10% gain is a fifth of the profit. Calculations that compare only entry and exit price overstate returns systematically, and the overstatement is worst on frequent small trades.

Volatility Is Not Symmetric

Drawdown	Gain needed to recover
−10%	+11%
−25%	+33%
−50%	+100%
−75%	+300%
−90%	+900%

Recovering from a loss takes a larger percentage than the loss itself, because the gain applies to a smaller base. This is why position sizing matters more than entry timing: a position that can fall 90% needs to multiply tenfold just to break even.

Custody

"Not your keys, not your coins" is not a slogan — Mt. Gox, QuadrigaCX, Celsius and FTX all lost customer assets held on their platforms.

Where	Control	Risk
Exchange	Theirs	Insolvency, freeze, hack
Hot wallet	Yours	Malware, phishing
Hardware wallet	Yours	Physical loss, seed exposure
Multisig	Shared	Complexity

A seed phrase is the asset. Anyone who reads it owns the funds, and losing it is unrecoverable — there is no reset.

Tax Follows Every Disposal

In the US the IRS treats crypto as property, so selling, swapping one token for another and spending it are all taxable events, whether or not dollars moved. Cost basis must be tracked per lot, per wallet. Without records the default assumption is a zero basis, which makes the entire proceeds taxable.
