Our verdict on Bigcoin
5.5/10Bigcoin may suit players who want a strategy game built around virtual mining rather than a passive token-reward product. Its strongest feature is the clear connection between miner attributes, facility limits and a player's share of block rewards, with merge mining adding another option. The main caveats are exposure to $BIG, changing rewards as network hashrate shifts, and limited published security and cost details. Review the current mechanics and transaction requirements before committing funds.

What is Bigcoin?
Bigcoin is an onchain mining game on Abstract inspired by Bitcoin. Players deploy NFT miners, upgrade facilities and earn $BIG based on their share of the game's total hashrate. It also offers merge mining, cosmetics and other game assets.
The original design described a 21 million $BIG supply cap, rewards that halve every 4.2 million blocks, and a burn of 75% of $BIG spent on miners and facilities. The documentation says the project later transitioned from its pseudonymous founder to community contributors, and that the game has expanded its mechanics. Treat those original token mechanics as design details, not as a promise of future rewards or token performance.
How Bigcoin works
Bigcoin replaces physical mining equipment with onchain NFT miners and virtual facilities. Miners have hashrate and power-consumption attributes, while facilities set limits on how many miners can operate and how much power the setup can use. Players use $BIG to buy miners and upgrade facilities, then compete for a share of the game's mining rewards.
6 features
Key features
01
NFT miners
NFT miners have hashrate, power consumption and a $BIG cost. Players use them to build virtual mining capacity.
02
Mining facilities
Facilities limit power output and miner capacity, adding resource constraints to how players build their setups.
03
Proportional rewards
Rewards are distributed per block according to each player's share of total network hashrate.
04
Merge mining
Players can switch to merge mining to unlock other tokens, though the available tokens and detailed mechanics are not specified here.
05
Token burns
The documentation says 75% of $BIG spent on miners and facilities is burned. This describes the original deflationary design and should not be treated as a guarantee of token value.
06
Cosmetic items
Mining-room cosmetics provide visual customization separate from the core miner and facility mechanics.
Pros and cons
What we like
- A clear game loop links miner selection, facility limits and hashrate to block rewards.
- The project runs on Abstract and describes its assets and mining as onchain.
- Merge mining offers an alternative to earning only $BIG.
- Cosmetics add customization without being described as part of the mining-reward calculation.
- The documentation explains several core mechanics, including proportional rewards and the original token-burn design.
Watch out for
- Mining rewards depend on your share of the network's total hashrate, so rewards may change as other players add miners.
- Buying miners and upgrading facilities requires $BIG, exposing players to the token's price and liquidity risks.
- The current documentation describes a community-led evolution of the project, but does not fully explain how all updated mechanics differ from the original game.
- Audit information, contract security details, and incident history are not published in the documentation.
- Fees and the current cost of miners and facilities are not stated.
Bigcoin fees
Bigcoin does not publish a separate platform fee schedule or current prices for miners and facilities. Players should check the game's interface for purchase costs and their wallet for any network transaction costs before confirming a transaction.
Is Bigcoin safe?
Bigcoin involves onchain assets and $BIG, so players face smart-contract, wallet, token-price and liquidity risks. Mining rewards are variable because they depend on each player's share of total hashrate; the game does not guarantee a return. An audit, detailed contract-security information and an incident history are not published in the documentation. The project is not described as a gambling service; users should still check local rules for crypto gaming and only participate if they are 18 or older, where applicable. Play responsibly and do not spend more than you can afford to lose.

Who Bigcoin is for
