A few months ago, a friend texted me a screenshot of his brokerage. He’d put $3,000 into a crypto position when Bitcoin was around $68,000 and his portfolio was now worth $1,800. His question was: “Should I hold or cut my losses?”
That’s the wrong time to be thinking about position sizing.
The right time is before you put a dollar in. Ask yourself calmly: if this position drops 60%, does it change my actual life? If yes, you’re probably in too deep.

What Crypto Actually Is and What It Isn’t
I’m not a financial advisor and I’m not here to tell you to buy or not buy Bitcoin. But I think it’s worth being honest about what you’re buying when you buy crypto.
Bitcoin has no earnings, no dividends, no intrinsic value in the accounting sense. It’s not like a stock, where you own a fractional claim on a company’s future cash flows. It’s closer to a commodity or a speculative monetary asset. Its value is driven by supply scarcity (there will only ever be 21 million Bitcoin), network effects, and demand.
That doesn’t make it worthless. Gold has no intrinsic value either, and it’s been a store of value for thousands of years. But it does mean the traditional frameworks for valuing assets don’t apply cleanly.
What you’re really betting on with Bitcoin is whether more people will want it in the future than want it now. That’s a belief about adoption curves, monetary policy, institutional demand, regulatory outcomes, and a dozen other variables none of us can predict with confidence.
Bitcoin was trading around $61,500–$64,000 in June 2026 (market data, June 2026). Institutional ETF inflows have kept price relatively stable compared to prior cycles, but “relatively stable” still means multi-thousand dollar swings in any given week.
The position sizing question is the only one that matters
Here’s the framework I use when people ask me about crypto: it’s not about whether Bitcoin is a good investment. It’s about how much you can afford to lose without wrecking your finances.
That number is almost always smaller than people think when they’re excited about a price move.
Let’s say Bitcoin drops 60% from where it is today, which has happened multiple times in its history (2018, 2020, 2022). A $5,000 position becomes $2,000. A $10,000 position becomes $4,000. A $25,000 position becomes $10,000. That’s what happens to money someone pulled from savings to “get in before it goes higher.”
At what loss number does your life actually change? At what number do you panic-sell and lock in the loss? That threshold is your real maximum allocation, not the number you can technically transfer from your bank account.
The rule I’ve seen work consistently: never put more than 5% of your investable assets into any single speculative position. For most people starting out, crypto shouldn’t be more than 1-5% of a portfolio. That’s not a rule, it’s a risk tolerance framework, and the right number is completely personal to your situation.
The tax math people forget
Cryptocurrency is taxed as property in the U.S. Every time you sell, trade, or use crypto, you have a taxable event (per IRS guidance, 2026).
Short-term gains (held less than one year) are taxed at ordinary income rates, typically 22-32% for most people. Long-term gains (held more than one year) are taxed at 0%, 15%, or 20% depending on your income.
This has a real implication for people who buy crypto and plan to sell when it doubles: a significant portion of that gain goes to taxes if you held it less than a year and you’re in a middle income bracket. The math on a 100% return can look very different after taxes.
Also: you owe taxes on gains even if you never see cash. If you trade Bitcoin for Ethereum, that’s a taxable event. If you use crypto to buy something, that’s a taxable event.
This doesn’t mean don’t buy crypto. It means build the tax cost into your return expectations.
How the calculator works
The Should I Buy Crypto calculator at Worth It Calculators isn’t a prediction tool. I didn’t build it to tell you Bitcoin is going to $100K or $20K.
What it does is walk you through the position sizing math:
- What percentage of your investable assets would you be putting in?
- If the position drops 50%, what’s the dollar loss?
- If it drops 80% (which has happened to crypto), what’s the dollar loss?
- Is either of those numbers a problem for your financial situation?
It also shows you the break-even return needed to recover various loss amounts, which is non-intuitive: a 50% loss requires a 100% gain to recover. A 60% loss requires a 150% gain.
The output isn’t “buy” or “don’t buy.” It’s a clearer picture of what you’re actually doing with your money before you do it.
Real-world scenarios
I’ve seen two common patterns in how people approach crypto:
Pattern 1: FOMO-driven allocation. Someone sees Bitcoin at $62K and remembers when it was at $20K, or hears a friend made money, and puts in more than they can genuinely afford to lose. When the price drops, they either hold through severe anxiety or sell at the worst possible time.
Pattern 2: Deliberate allocation. Someone decides crypto is worth 2-3% of their investment portfolio. They buy that amount, mentally write it off as they would any high-risk position, don’t look at the price daily, and let the long-term thesis play out, one way or the other.
Pattern 2 has much better outcomes, not because crypto went up (it might not), but because the person isn’t emotionally tormented by their position size and doesn’t make panic decisions.
Common mistakes
Buying on a spike. The worst time to buy anything is when you just saw a 20% move up and are scared of missing it. The best time is when you’ve already decided your allocation and the price happens to be reasonable.
Treating exchanges as wallets. Exchange collapses have been painful reminders that “not your keys, not your coins” is a real principle. If you’re holding a meaningful amount of crypto, a hardware wallet is worth understanding.
Confusing coins. Bitcoin and Ethereum are meaningfully different from thousands of altcoins that have gone to zero. The scarcity and network effect arguments that apply to Bitcoin don’t automatically apply to anything else.
Ignoring the tax account. When you have gains, set aside 25-35% in a separate account before you spend or reinvest. Crypto taxes catch people off guard.
FAQ
How much of my portfolio should be in crypto? There’s no universal answer, but 1-5% is a common range for a speculative position that won’t wreck you if it goes to zero. If you find yourself wanting to put 20-30% in crypto, that’s usually FOMO-driven, not strategy-driven, and worth examining.
Is it too late to buy Bitcoin? Nobody knows. People said “too late” at $1,000, $10,000, $30,000, and $60,000. Some of them were wrong; some were right for a while. The “too late” framing assumes a specific price target that nobody can actually predict.
What’s the difference between Bitcoin and other cryptocurrencies? Bitcoin has the most established network, the most recognized scarcity model, and the most institutional adoption. Other cryptocurrencies have different use cases, risk profiles, and team structures. They’re not interchangeable assets. Research what you’re buying.
The bottom line
Crypto is real. The returns are real. The losses are also real.
The only question that matters before you buy is: how much can you lose without it affecting your financial stability or your peace of mind? That number is your allocation. Everything else is noise.
Before you decide on an allocation, it’s worth knowing what that same money would grow to risk-free over time. The compound interest calculator puts the opportunity cost in context. And if a crypto loss would delay a financial goal, the savings goal calculator will show you by how much.
