Crypto balance simulator: compose a wallet balance that adds up
The big number on a wallet screen is not typed. It is quantities times live prices, plus cash, with a day change that follows from them. Here is how to land near the figure you need, in the browser, then on your own phone.
Published:
A crypto balance simulator composes the balance on a wallet screen: you type quantities, live prices turn them into dollar values, and the total and its 24-hour change are summed from those rows. My Larp Wallet does it in the browser and opens the result full screen on your phone; it holds no funds, and the screen is a mockup, never proof of a balance.
What people mean by a crypto balance simulator
The phrase covers three different tools, and only one of them draws a balance on a wallet screen.
- A paper trading account. Virtual money you trade at market prices, to practice. The balance moves because of your trades. If that is what you are after, the demo account, paper trading and wallet simulator comparison sorts the options.
- A wallet balance simulator. A wallet screen whose holdings you type: the tool multiplies them by market prices and adds them up. Nothing is traded and nothing is held. This page is about this kind, and My Larp Wallet, a crypto wallet app simulator, is one of them.
- A "balance adder" for a real wallet app. Downloads that claim to put a balance inside an installed wallet. A modified wallet app is exactly how the FakeWallet campaign described by Kaspersky in April 2026 stole recovery phrases, and the stated purpose of such a tool is to deceive. Stay away from them.
What a simulator is in general, and where its limits are, is covered in what a crypto wallet simulator is. This page stays on the one number at the top of the screen.
The balance is a sum of rows
On a wallet's home screen, the large number is computed, not entered. Each token row is quantity × price, the total is the rows plus any cash, and the day change under it is the sum of each row's own change. In our simulator, the five built-in tokens (SOL, ETH, BTC, HYPE and USDC) take both their price and their 24-hour percentage from the market, refreshed every 4 seconds. A custom token keeps the price and the change you type. For a built-in token, the only figure you choose is the quantity.
How to order the rows and shape the allocation is in how to make a crypto portfolio mockup that adds up. The question here is narrower: the header has to read about a given figure. How do you get there?
Worked example: landing near $24,700
Say a video needs a wallet worth roughly $24,700. Decide what each row should be worth, with uneven figures, divide each by its live price and type the result as the quantity. The prices below were read from public market data on October 12, 2026, around 12:35 UTC. They are an example, not a quote.
| Token | Value wanted | Live price | Quantity typed | Row shows | 24h | Row change |
|---|---|---|---|---|---|---|
| SOL | $10,874 | $110.41 | 98.48746 | $10,874.00 | +0.74% | +$79.77 |
| ETH | $6,931 | $2,532.78 | 2.73652 | $6,931.00 | +1.09% | +$74.68 |
| BTC | $3,968 | $83,002.01 | 0.04781 | $3,968.33 | -0.17% | -$6.70 |
| HYPE | $1,412 | $85.11 | 16.59029 | $1,412.00 | -0.22% | -$3.06 |
| USDC | about $1,188 | $1.0008 | 1,187.35 | $1,188.30 | -0.01% | -$0.12 |
The rows come to $24,373.63. Add a cash row of $318.40 and the header reads $24,692.03. Its change is the sum of the row changes, +$144.58, and its percentage is that change divided by yesterday's balance: 144.58 / (24,692.03 - 144.58) = +0.59%. Not the average of the five percentages (+0.29%), and not the +1.09% of the ETH row.
Each row change follows one rule: value - value / (1 + pct), with the market's exact percentage (SOL's +0.74% was +0.739% before rounding). The SOL row gained $79.77, not the $80.36 you get by taking 0.739% of today's $10,874.00, because the percentage applies to yesterday's value.
Look at the cents. Divide a target by a price, type the result, and the row hands your target back to the cent: $10,874.00, $6,931.00, $1,412.00. Three rows ending in .00 is a pattern a viewer notices. It lasts until the next price tick, so on a still taken in the first seconds, wait for one or nudge the last digit of a quantity.
A live balance does not hold still
Every 4 seconds the built-in prices refresh, and the header follows. With 98.48746 SOL on screen, each $0.10 move in SOL moves the balance by $9.85; each dollar on ETH moves it by $2.74. A recording shows a header ticking a few dollars at a time, the way an app does, while every quantity stays what you typed.
The settings also let you type the total yourself: the Total balance field, which adds up tokens and cash when left empty. It is the fastest way to a figure and the first thing to break on video. A typed total stays at, say, $25,000.00 while the rows under it add up to $24,692.03 and keep moving, so anyone who adds them finds a $307.97 gap. The Change ($) and Change (%) fields behave the same way: typed, they stop following the market. Keep them for a still where the rows are off screen, and let the app compute everything else.
Rounding: what the screen shows and what it multiplies
The list shows five decimals below 1,000 units and two from 1,000 up, which is why the USDC row reads 1,187.35 and the SOL row 98.48746. The value, however, is computed from the quantity you typed, not the one displayed. On most tokens the difference is invisible. On BTC it is not: 0.00001 BTC was worth about $0.83 that day.
Type 0.047806 BTC and the row shows 0.04781 BTC worth $3,967.99. Multiply what is visible, 0.04781 × $83,002.01, and you get $3,968.33: thirty-four cents off, which is the kind of gap a careful viewer finds. Type no more decimals than the list displays, and every row checks out on a calculator.
Round quantities fail the other way. 10 ETH or 100 SOL reads as typed, because real holdings are what is left of purchases made in dollars, at prices with decimals, minus fees.
An online simulator that opens like an app
For us, "crypto wallet simulator online" and "crypto wallet simulator app" are the same thing. My Larp Wallet is a web app:
- Compose in any modern browser, on a computer or on the phone itself: tokens, quantities, wallet name, avatar, accent colour.
- Open it on your phone at your own address, mylarpwallet.com/yourname. On iPhone: Safari, Share, Add to Home Screen. On Android, Chrome offers Install app or Add to Home screen. It then opens full screen, with no browser bar.
- Shoot it on the phone. There is no export: you take the screenshot or the screen recording yourself, at the phone's native resolution. The wallet draws no status bar of its own, so the time, battery and signal are your phone's real ones.
- Reopen it anywhere. The wallet is saved to your account, so the same balance opens on another device.
There is no APK, no IPA and no store listing, which is a safety point as much as a convenience. Kaspersky's FakeWallet report (April 2026) describes trojanized wallet apps pushed through lookalike pages, enterprise provisioning profiles on iPhone and phishing pages on Android, built to read recovery phrases. Google's Play Protect help page explains that it can block apps from higher risk sources, such as a web browser or a messaging app, when they ask for sensitive permissions. A balance screen needs none of that, as the APK and IPA question explains in detail.
Searches that name a specific wallet app
Many searches ask for a simulator of one named wallet; "phantom wallet simulator" is the most frequent of them in the search suggestions we collected. We do not reproduce any publisher's interface, logo or name. Section 3 of our terms forbids reproducing a third-party publisher's branding, trade mark or name in a way that creates confusion about the origin of a product, and a balance does not need a borrowed brand to read right.
What those searches usually want is a Solana-first balance, which the built-in SOL and USDC rows cover, with any other Solana token added as a custom row. The details are in the Solana wallet simulator post.
What a simulated balance is for
| Use | Fits? | Why |
|---|---|---|
| An explainer video or a lesson on how a wallet works | Yes | The balance illustrates; nobody is asked to believe it is yours |
| A pitch or a user test for a wallet app with no users yet | Yes | The screen is presented as a design |
| A film or a sketch where a character checks a phone | Yes | A prop, read as fiction |
| A post captioned as your real portfolio | No | It claims holdings you do not have |
| Proof of funds for a landlord, a lender or a seller | No | A typed figure presented as a record |
| A screenshot used to sell a course, signals or "account management" | No | It obtains money on a fictional position |
Where a simulated balance becomes fraud
The image is identical on both sides of the line; the claim attached to it is what changes. Section 3 of our terms forbids using a screen to make anyone believe you hold assets you do not hold, to obtain a payment, an investment, a loan or any other advantage on the strength of a fictional position, or to serve as evidence, a statement or a certificate. A breach ends the licence without refund.
It is also why a balance on a screen is never proof. The FTC describes investment scams that steer victims to a site that "looks real, but it's really fake", with an "investment account" they cannot withdraw from: a balance shown, not held. A real balance is checked on the chain, through an address on a block explorer tied to its holder by a message signed from that wallet. What lenders, landlords and brokers actually accept is listed in crypto proof of funds.
Used as what it is, a composed balance only has to add up. Every screen My Larp Wallet draws is a mockup: it connects to no wallet, asks for no seed phrase and holds nothing. See how the wallet is composed on the homepage.

Questions
Is a crypto balance simulator the same as a paper trading account?
No. A paper trading account gives you virtual money to trade at market prices, and its balance moves because of your trades. A wallet balance simulator draws a wallet screen from quantities you type and multiplies them by market prices. Nothing is traded and nothing is held, so it teaches what a wallet looks like, not how to trade.
How do I get a specific total balance in a wallet simulator?
Decide what each row should be worth, using uneven figures, divide each by the token's live price and type the result as the quantity. The total is then the sum of the rows plus cash. You can also type the total directly, but a typed total stops following the rows, which keep moving with the market every 4 seconds.
Does a simulated crypto balance change on its own?
In My Larp Wallet, yes for the five built-in tokens (SOL, ETH, BTC, HYPE and USDC): their price and 24-hour change refresh from the market every 4 seconds, so the total moves while your quantities stay fixed. A custom token keeps the price and the change you typed.
Can I use a crypto wallet simulator online without downloading an app?
Yes. My Larp Wallet runs in any modern browser and has no APK, no IPA and no store listing. On a phone you add it to the home screen from Safari or Chrome, and it then opens full screen like an app, at your own address.
Can a simulated crypto balance be used as proof of funds?
No. The figure was typed, nothing on the screen can be checked on a blockchain, and our terms forbid presenting the screen as evidence, a statement or a certificate. A real balance is shown by an address on a block explorer, tied to its holder by a message signed from that wallet.
