Position Sizing for Crypto — How Much Is Too Much?
Position sizing is one of those concepts that sounds boring until you blow up a large portion of your net worth because you didn't have one.
It's not about picking the right coins. It's about deciding how much of your money goes into each bet — and making sure no single position can do permanent damage if it goes wrong. For crypto, where 80% drawdowns are a historical baseline, this is the whole game.
Start With Your Total Crypto Allocation
Before you think about individual positions, you need to decide how much of your overall financial picture is in crypto at all.
There's no universal right answer, but here's a reasonable framework:
| Risk Tolerance | Crypto as % of Net Worth | |----------------|--------------------------| | Conservative | 1–5% | | Moderate | 5–15% | | Aggressive | 15–25% | | High conviction | 25%+ (with eyes open) |
"High conviction" doesn't mean reckless — it means you understand the asset, have a long time horizon, and are genuinely prepared to see that allocation drop 70% without making panic decisions.
If losing your entire crypto allocation would derail your financial life — rent, emergency fund, retirement timeline — you're either over-allocated or haven't separated spending money from investment capital.
Core rule: only invest what you can genuinely afford to lose entirely and not have it matter. Not "not matter much." Actually not matter.
Sizing Across Multiple Assets
Once you have your total crypto budget, you need to decide how to split it across individual assets.
A few common approaches:
The Concentrated Approach (2-4 Assets)
Put the majority of your crypto allocation into 2-4 high-conviction assets. Something like:
- 50-60% in a large-cap base (BTC, ETH)
- 30-40% in 2-3 specific altcoins you've researched
- Small satellite positions (5-10%) in more speculative names
Pros: Simple to manage. Forces real conviction. Fewer positions means you actually track each one properly. Cons: Less diversification. If your altcoin thesis is wrong, it hurts.
The Tiered Approach (5-10 Assets)
Tier 1 (largest positions): BTC, ETH, or other large-caps — your "stable" base in a volatile asset class. Tier 2 (mid-size): High-conviction plays you've researched. XRP, HBAR, XLM, or whatever fits your thesis. Tier 3 (smaller): More speculative, earlier-stage, or higher-risk positions you size accordingly.
Sizing each tier: Tier 1 positions might be 20-30% of your crypto allocation. Tier 2 might be 5-15% each. Tier 3 positions are typically 1-5% — small enough that if they go to zero, you shrug.
Pros: Spreads risk. Still allows for big movers to matter. Cons: More complex to manage. Risk of spreading conviction too thin.
The Maximum Single-Position Rule
Here's a practical rule: no single altcoin position should be large enough that it going to zero would materially damage you.
What counts as "materially damage"? If a complete wipeout of that position would:
- Significantly affect your retirement outlook
- Require you to delay major life plans
- Create real financial stress
...it's too big.
A coin can go to zero. Projects fail. Teams exit. Regulations change overnight. You want a portfolio where you're devastated about the price but not about your life.
For most people, this means individual altcoin positions in the 2-10% range of their crypto allocation — and their crypto allocation is already a reasonable portion of net worth, not all of it.
Don't Ignore Correlation
One of the least appreciated risks in crypto portfolios: everything is correlated.
When the crypto market crashes, it crashes across the board. XRP, HBAR, XLM, BTC — they all go down together, often simultaneously and severely. Owning 10 different crypto assets does not give you the same kind of diversification that owning 10 different stocks in different industries does.
This means:
- Your crypto "diversification" protects against a single project failing, not against a market-wide bear.
- True portfolio diversification has to happen outside of crypto, not just within it.
- When sizing your total crypto allocation against your net worth, treat the whole thing as one correlated position.
Sizing Around Conviction, Not Just Risk
Position sizing should also track your actual conviction level — meaning how deeply you've researched an asset and how much you believe in its thesis.
If you've done the work on XRP — you understand the payment rails thesis, the ISO 20022 angle, the ODL use case — that's a position that deserves real size in your crypto allocation.
If you heard about something on Twitter three days ago, that's a 1-2% speculative position, not a 20% holding.
The discipline is matching position size to the quality of your reasoning, not to your excitement level. Excitement and conviction feel the same in the moment. They're not the same thing.
Rebalancing: When to Adjust
Crypto moves fast. A position that was 10% of your portfolio can become 30% after a strong run — and 5% after a correction.
A few rebalancing approaches:
Calendar rebalancing: Review allocations every quarter or every 6 months and trim or add to get back to targets.
Threshold rebalancing: If any single position exceeds a set percentage (say, 25% of your crypto allocation), trim it back.
Cycle-aware rebalancing: Reduce altcoin exposure as you move into what looks like late-cycle territory. Shift to larger-caps or stablecoins.
Rebalancing is a way of automating the "sell high, buy low" behavior that's hard to execute emotionally. If something runs 5x and becomes an uncomfortably large share of your portfolio, trimming it back isn't giving up — it's risk management.
The "Sleep Test"
There's a simple, underrated sanity check for position sizing: if your portfolio dropped 50% tomorrow, could you sleep? Could you go about your normal week?
If the honest answer is no — if you'd be checking prices every hour, unable to focus, tempted to panic sell — you're over-positioned. The problem isn't the market. It's that you put in more than you can emotionally handle.
Sleeping fine during a bear market is a superpower in crypto. It's almost entirely determined by how you sized in.
Bottom Line
Position sizing is one of the highest-leverage decisions you make as a crypto investor. It determines whether you stay in the game long enough to benefit from your thesis, or whether one bad cycle forces you out at the worst possible time.
The framework is simple: size your total crypto exposure based on your actual financial situation. Size individual positions based on conviction, not excitement. Keep single positions small enough that going to zero hurts your wallet but not your life.
The math of "right position size" varies. The principle doesn't.
