How much is $100 worth in crypto? — What $100 buys in crypto
How much is $100 worth in crypto? A practical guide for real people
Imagine you have a crisp $100 bill and you want to know how much crypto can I buy with $100. That question is simple to ask but requires a few moving parts to answer well: the live spot price, the trading fee you pay, any slippage or spread, and the on-chain costs or withdrawal rules you’ll face. This guide walks through all of those pieces in plain language and gives a reliable calculation you can use right now.
Short answer up front: for USD-pegged stablecoins, $100 usually becomes almost 100 tokens minus tiny fees. For Bitcoin or Ethereum, $100 buys only a fractional piece — often a few thousandths of BTC or a few hundredths of ETH after fees and spreads.
$100 is a common entry point: small enough to feel manageable but large enough that fees and withdrawal costs matter. Asking “how much crypto can I buy with $100” teaches you the mechanics of trading, custody, and on-chain movement without risking a large sum. That primer helps you make smarter choices when you scale up later.
One reliable formula
Keep this formula handy: net_amount = (USD_to_spend – trading_fee – estimated_slippage – withdrawal_or_gas_if_withdrawable) / spot_price. For stablecoins with a peg of 1.00, that simplifies to about USD_to_spend minus fees. For volatile assets the denominator (spot_price) makes a big difference.
Step-by-step: how to use the formula
Before you click buy, run these quick steps so you know what your real outcome will be when you ask “how much crypto can I buy with $100”:
1. Check the live spot price for the token.
2. Look at the exchange’s visible trading fee (maker/taker or flat fee).
3. Estimate slippage or spread (0.1–2% for liquid pairs; higher for thinly traded alts).
4. If you plan to withdraw, add withdrawal or on-chain gas costs. Subtract those from $100 and divide by the spot price.
That’s it – simple math, clearer expectations.

What $100 commonly bought in 2024–2025
Market prices fluctuate, so think in ranges. In 2024–2025 conditions, asking how much crypto can I buy with $100 typically returned these orders of magnitude:
– Bitcoin: roughly 0.001–0.005 BTC depending on price swings.
– Ethereum: roughly 0.03–0.12 ETH depending on where ETH was trading.
– Stablecoins: roughly 99–100 tokens minus minor fees.
Those are examples, not guarantees. The exact amount depends on the spot price and the fees you face the moment you trade.
Fees, spreads, and slippage: the invisible costs
When you ask “how much crypto can I buy with $100” it’s tempting to use the mid-market price, but the real executed price includes the bid–ask spread and any slippage. Major centralized exchanges often advertise trading fees from zero to around 0.6% for retail trades. That might be small numerically, but on a $100 buy it still reduces what you receive.
Decentralized exchanges (DEXs) present costs differently: execution happens against liquidity pools and the cost shows up as slippage plus protocol fees. On a DEX you’ll also pay network gas. For small buys, those extra costs can be a larger percentage of the total than the token exposure itself.
Worked example: Bitcoin
Suppose BTC trades at $40,000 when you buy. If you ignore fees, $100 / 40,000 = 0.0025 BTC. But you rarely avoid fees. If the exchange charges 0.2% and you estimate 0.5% slippage, then
net_amount = (100 – 0.20 – 0.50) / 40,000 = 99.30 / 40,000 ≈ 0.0024825 BTC.
On a day when BTC is $25,000, the same math gives 99.30 / 25,000 ≈ 0.003972 BTC. The steps are the same; the spot price changes the result.
Worked example: Ethereum (and gas fees)
For ETH at $2,500, the same 0.2% fee and 0.5% slippage give about 99.30 / 2,500 ≈ 0.03972 ETH. But if you plan to withdraw directly to your own wallet, on-chain gas can add another substantial cost. A $10 gas fee effectively reduces your $100 purchase by 10% if you pay that from the purchase itself, so plan carefully.
Stablecoins: the near 1:1 case
Stablecoins like USDT and USDC aim to stay near $1.00. So when someone asks “how much crypto can I buy with $100” and they mean stablecoins, the realistic outcome is close to 100 tokens minus fees. That makes them useful on-ramps or temporary parking spots while you decide what to do next.
Custody and minimums that affect value
Exchanges may have minimum withdrawal amounts or fixed withdrawal fees. A $5 withdrawal fee on a $100 buy is a 5% hit. Similarly, some services auto-convert dust or charge maintenance that quietly reduces balances. Those policies matter when your purchase is small.
CEX vs DEX: where should you buy?
If you’re wondering “how much crypto can I buy with $100” choose your venue carefully. Centralized exchanges (CEXs) often give a cleaner fiat on-ramp and predictable maker/taker fees. Decentralized options can be cheaper for token-to-token swaps if you already hold crypto, but they expose you to slippage and gas. For first-time fiat buys, many people find CEXs easier and cheaper overall. For broader context see our crypto hub.
Practical tips to stretch $100
Here are simple steps to keep more value in your pocket when you ask “how much crypto can I buy with $100”:
1. Use limit orders when possible. A limit order can avoid taker fees and sometimes gives a better fill price. The trade-off is it may not execute immediately.
2. Avoid immediate withdrawals if you don’t need on-chain access right away — holding on a trusted exchange avoids withdrawal gas and fixed fees.
3. Prefer stablecoins for short-term parking. Converting to USDC or USDT keeps value stable and is usually cheap.
4. Check liquidity for altcoins. If a token is thinly traded, slippage can wipe out a large share of a $100 buy.
5. Time your transfer costs. On congested chains, waiting for lower gas windows can save dollars on small buys.
A short real-world story
I once swapped $100 on a DEX into a hyped alt and watched slippage and gas shave nearly 10% off the expected amount. That first small trade taught me to always check liquidity and slippage settings before swapping. Lessons like that make the question “how much crypto can I buy with $100” more than a math problem – it becomes a habit of careful trading.
Use a limit order or trade on an exchange with low maker fees and avoid immediate on‑chain withdrawals; this minimizes taker fees and gas so your $100 converts to the most tokens possible.
Answer: Use a limit order or buy on an exchange with low maker fees, and avoid on-chain withdrawals until you’ve accumulated enough value to justify the gas. That often gives you the best ratio of tokens to dollars for small purchases.
How to calculate your own net amount (quick checklist)
1. Note the spot price.
2. Subtract the explicit trading fee from $100.
3. Subtract a slippage/spread estimate (0.1–2% for liquid pairs).
4. If you will withdraw, subtract the withdrawal fee or expected gas.
5. Divide the leftover USD by the spot price.
Example: A $100 BTC buy with 0.2% fee and 0.5% slippage at $40,000 gives about 0.00248 BTC. For stablecoins it’s usually $100 less fees – roughly 99–100 tokens.
Common questions people ask
Will $100 ever buy a whole Bitcoin?
Not unless BTC falls to $100. Instead, think in fractions. Fractional ownership is normal in crypto: your 0.0025 BTC is just as valid as anyone’s full BTC, and can appreciate or depreciate with the market.
Is it worth buying $100 of crypto?
It depends on your goal. For learning, $100 gives hands-on experience. For serious investing, small sums mean fixed fees and withdrawal costs eat more of your exposure, so consider whether you’ll do regular purchases (dollar-cost averaging) or save up for a larger buy.
Do I need a wallet to buy?
No – you can hold on an exchange. But if you want private keys and full control, you’ll eventually move to self-custody and pay on-chain fees to do so.
How much will I lose to fees?
Expect anything from a few tenths of a percent to several percent depending on withdrawal and gas costs. On a $100 buy, a $10 gas charge is a 10% hit; a $5 fixed withdrawal is 5%.
What about taxes?
Taxes differ by country. Keep records of purchase price, fees, and timestamps; these are the basics for reporting capital gains or losses in many jurisdictions.
Smart ways to experiment with $100
If your goal is to learn, try these low-risk experiments:
– Buy a stablecoin to practice transfers between platforms.
– Buy a tiny fraction of BTC or ETH and track the effect of fees over months.
– Use a DEX on a low-fee chain to learn swaps without spending large amounts on gas.
Each experiment teaches you different parts of the ecosystem and prepares you to answer “how much crypto can I buy with $100” with more confidence over time.
When tiny amounts make sense – and when they don’t
Small trades are great for learning and for getting started. But if your priority is minimizing fees relative to exposure, consider accumulating into larger purchases or doing regular dollar-cost averaging so the fixed parts of costs are spread across many buys rather than concentrated in one tiny transaction.
Checklist before clicking buy
– Live spot price noted?
– Visible trading fee checked?
– Slippage estimate set?
– Withdrawal or gas cost checked?
– Minimum withdrawal enforced by exchange checked?
Answering these saves surprises and helps you get more value for your $100.

Parting tips
If you’re about to make that first $100 purchase, pause: check the visible trading fee, set a realistic slippage estimate, and decide whether you’ll withdraw now or later. A little attention keeps that $100 experiment honest and often leaves you with a few more satoshis or a bit more ETH than you might otherwise get.
Good luck, and enjoy the learning curve – small bets that are well understood often teach the best lessons.
Only if Bitcoin’s market price falls to $100. Today, BTC trades far above that, so a $100 purchase will buy a fractional share (satoshis). Fractional ownership is normal and fully supported by exchanges and wallets.
Not always. Withdrawing to your own wallet often incurs fixed withdrawal fees or on‑chain gas that can be a large percentage of a $100 buy. If you don’t need immediate on‑chain access, holding on a trusted exchange can avoid those costs until you’ve accumulated a larger amount.
Use a limit order or trade on an exchange with low maker fees, avoid immediate withdrawals to save on gas or fixed fees, and stick to liquid tokens or stablecoins. Also consider timing transfers for lower network congestion to reduce gas costs.
