Frequently Asked Questions
1. Why are my earnings constantly changing?
Earnings in RollerCoin are not static. The 'Network Power' of your chosen coin changes second by second. When other players allocate their power to that coin or buy new miners, the total network power increases. Even if your personal power remains constant, your share of the pie decreases because the total pool got larger. Additionally, due to crypto market volatility, the USD equivalent of your earnings changes live.
2. How do I know which league I am in?
You are assigned a league based on your total active 'League Power' in the game. When you enter your Username in our calculator to fetch data via the API, the tool automatically detects the exact league assigned to you by the game. If you are entering your power data manually, the calculator in 'Auto' mode places you in the approximately correct league based on your hash power sum. If it's incorrect, you can change your league manually from the dropdown menu.
3. Which coin is the most profitable to mine?
There is no single correct answer for this because reward rates and the market price of coins (e.g., BTC, SOL, DOGE, etc.) change constantly. By looking at the USD column in our 'Earnings' table, you can see in seconds which coin offers the highest fiat return under the current network conditions. Remember, the highest USD yielding coin is generally the most logical choice, but you should also factor in the future potential price appreciation of that coin.
4. How does the Withdraw Timer work?
This tool takes your current balance in the game and your real-time production (earning) rate to calculate exactly how many days and hours it will take for you to reach the minimum withdrawal limit for that specific coin. Since this calculation is based on current network power, an increase in network power might extend the withdrawal timeline.
5. What is the Power Simulator used for?
If you are planning to spend your RLT or crypto to buy a new Miner or Rack, this tab allows you to simulate the purchase. When you enter the new hardware's Raw Power and Bonus Percentage, it adds it to your existing power and instantly shows what your new total power and new earnings will be. This helps you avoid making unprofitable miner purchases.
6. How often is the data updated?
When you fetch data via the API (using your username or the 'Fetch Data' button), all league powers, block rewards, and block durations are pulled directly from the RollerCoin servers in real-time. Cryptocurrency prices are fetched from the Binance exchange API (with CoinGecko as a fallback) and reflect the live market rates at that exact moment. The data is cached locally for 5 minutes to avoid excessive API calls.
7. Why does my league change automatically?
The calculator has an 'Auto League' detection feature. Based on your total qualifying power (Miners + Bonus + Rack power, excluding Games/Temp/Freon), it automatically places you in the correct league tier. If the auto-detection is incorrect or you want to explore a different league's earnings, you can disable 'Auto' mode and manually select any league from the dropdown menu.
8. What is the difference between 'Current Power' and 'Max Power'?
'Current Power' includes ALL power sources: Miners, Racks, Games (mini-game power), Temporary Power, Freon, and Bonuses. This is the total power used for block reward calculations. 'Max Power' (or League Power) only includes Miners + Racks + Bonus power and determines which league you belong to. Games, Temporary, and Freon power do NOT affect your league placement but do increase your mining earnings.
9. Can I use this calculator on mobile devices?
Yes, the calculator is fully responsive and works on all modern mobile browsers including Chrome, Safari, and Firefox. The interface automatically adapts to smaller screens with touch-friendly controls. You can also install it as a Progressive Web App (PWA) on your home screen for quick access.
10. What are League Charts and how do I use them?
League Charts show the historical trend of average network power and block payout for each league over time. You can select any league and cryptocurrency combination, then filter by date range (7 days, 30 days, or all time). This helps you identify patterns — for example, if a league's power is steadily increasing, your individual share of rewards will decrease proportionally. Use this data to decide which league to target or when to switch coins.
11. How does the Merge Calculator work?
The Merge Calculator displays all available miner merge recipes from RollerCoin's crafting system. Each recipe shows the resulting miner, its power, bonus percentage, RLT cost, and required parts. You can set your Forge level (1-5) to apply the correct component discount, adjust merge count for bulk calculations, and set custom marketplace prices for components to get accurate total cost estimates. The tool helps you decide whether a merge is worth the investment before spending your RLT.
12. What is a Progression Event and how does the event calculator help?
Progression Events are limited-time events in RollerCoin where you earn points by spending RLT (through marketplace trades or direct exchange) to unlock exclusive rewards at each level. Our event calculator shows all reward tiers, the RLT cost per level, multiplier calculations, and box opening costs. It helps you plan your budget before the event starts so you can decide how many levels you can afford and whether the rewards justify the investment.
13. What cryptocurrencies does the calculator support?
The calculator supports all mineable cryptocurrencies in RollerCoin: Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Dogecoin (DOGE), BNB, Litecoin (LTC), XRP, Tron (TRX), and POL (Polygon/MATIC). It also calculates in-game token earnings for RLT, RST, and HMT. USDT earnings are shown but since it's a stablecoin, its price is fixed at $1. All coins except ALGO and USDT appear in the withdrawal timer since they can be withdrawn from the game.
14. What is 'Block Duration' and why does it matter?
Block Duration (or Block Time) is the number of seconds between consecutive blocks being mined for each cryptocurrency. The default is approximately 600 seconds (10 minutes), but it varies by coin and can change over time. Shorter block times mean more blocks per hour, which means more frequent (but smaller) rewards. The calculator fetches current block durations from the API automatically, but you can switch to manual mode in Settings to override them.
15. Why do some coin prices show differently than on exchanges?
Prices are fetched from Binance API by default (with CoinGecko as a fallback option). Minor differences from other exchanges are normal due to slight price variations across platforms. If Binance is blocked in your region, you can switch to CoinGecko in the Settings modal. The price is used only for the USD equivalent column — your actual crypto earnings remain the same regardless of which price source is selected.
16. How do I install the calculator as a PWA (Progressive Web App)?
On Chrome (desktop or mobile), look for the install icon in the address bar or the 'Add to Home Screen' option in the browser menu. On Safari (iOS), tap the share button and select 'Add to Home Screen'. Once installed, the calculator opens like a native app, loads faster, and works even with limited connectivity since the service worker caches essential assets.
17. How accurate is the calculator compared to actual in-game earnings?
The calculator provides a close estimate based on real-time data from RollerCoin's API. However, actual earnings can vary slightly because: (1) network power changes constantly as players join/leave, (2) block times fluctuate around the average, (3) there may be brief server-side maintenance periods. For the most accurate results, fetch fresh data frequently using the 'Refresh' button.
18. What are Game Tokens (RLT, RST, HMT) and why are they shown separately?
Game tokens are in-game currencies with no external market price. RLT (RollerToken) is used for marketplace purchases, event participation, and miner crafting. RST is a secondary game token. HMT is used for specific in-game mechanics. Since they have no real-world USD value on exchanges, they are displayed in a separate tab from cryptocurrencies. Their block rewards and earning rates are still calculated using the same formula.
19. What is Collection Bonus and how does it affect earnings?
Collection Bonus is a percentage multiplier applied to your total miner power based on the unique miners in your collection. Each distinct miner model you own adds its bonus percentage to a cumulative total. For example, if you have 5 unique miners with bonuses of 1%, 2%, 1.5%, 0.5%, and 3%, your total collection bonus is 8%. This 8% is applied to your raw miner power to give you 'free' extra hash power. The Power Simulator accounts for this when you add new miners.
20. Does this site collect my personal data or RollerCoin credentials?
No. We do not have any database and do not store any personal information. Your RollerCoin username is only used to fetch publicly available profile data from the game's API — we never ask for or handle your password or login credentials. All calculations happen client-side in your browser. The only data stored locally (in your browser's LocalStorage) are your preferences like language, league selection, and cached calculation results.
21. What are Daily Bonus Quests?
Daily Bonus Quests are daily challenges in RollerCoin that offer additional rewards when completed. Our tool fetches and displays the current active quest including its description, required action, reward type, and Season XP bonus. You can also view quest history to track past quests and their rewards.
