The Big Coin IEO funded a BEP-20 token marketed with unusually vague language, positioning itself as "not just a token, but a belief" that would "revolutionize digital transactions" and reward long-term holders. Despite this thin marketing substance, BCX reached a genuine BitMart listing and an all-time high of $4.99, a surprisingly strong outcome for a project with so little concrete product detail. This review documents the sale, a specific technical risk factor confirmed on-chain, and the token's dramatic decline since its peak.
Big Coin describes itself simply as a BEP-20 smart chain token "designed to deliver substantial returns to its investors," with holders receiving unspecified "significant rewards for their loyalty" that increase the longer tokens are held. Beyond this general loyalty-reward framing, this review found no detailed whitepaper, roadmap, or specific product description setting out how BCX generates value beyond speculative trading itself.
CoinGecko's own listing explicitly flags that "Big Coin (BCX) has recently migrated from their old contract to a new contract," and separately notes: "According to GoPlus, this is a proxy contract. The contract owner can make code changes to the token contract including but not limited to disabling sells, changing fees, minting, transferring tokens etc." This is a specific, verifiable technical finding, not speculation, and represents a genuine centralization risk: the deployed contract structure gives whoever controls it the ability to alter core token behaviour after the fact, including the ability to prevent holders from selling.
Despite the vague marketing and confirmed proxy risk, BCX did reach a centralized exchange listing, trading actively on BitMart with the BCX/USDT pair showing meaningful daily volume in the range of $15,000 to $18,000. Total supply is capped at 50 million tokens, with the current fully diluted valuation sitting in the low hundreds of thousands of dollars.
Big Coin's presale-to-BitMart-listing outcome is a genuine achievement relative to the many unlisted tokens documented throughout this catalogue, and its brief run to a $4.99 all-time high suggests real speculative demand existed at some point. However, the combination of exceptionally thin, generic marketing substance and a confirmed, verifiable proxy contract risk (independently flagged by both CoinGecko and GoPlus's automated security scan) means this project carries a documented technical vulnerability beyond typical market volatility.
BCX trades today with substantial price disagreement across sources: figures range from a fraction of a cent up to roughly $0.04-$0.08 depending on the tracker and moment, according to CoinGecko, a decline exceeding 99.9% from its $4.99 all-time high regardless of which current figure is used. The most active pair remains BCX/USDT on BitMart. Full trading data is viewable at BitMart.
Given the confirmed contract migration and proxy-contract structure, current holders and prospective buyers should independently verify the currently active, correct contract address directly through BitMart or CoinGecko before any transaction. For a comparison against another BEP-20 token with confirmed technical risk flags, see the Gas Wizard ICO, or browse the OilXCoin presale review for currently active presales.
Treat the following as mandatory checks: an independent, automated GoPlus security scan confirms the current contract owner retains the ability to disable sells, change fees, or mint additional tokens, a serious and verified centralization risk; the project underwent a confirmed contract migration, so verify you are viewing data for the current, correct contract address rather than the deprecated original; and the project's marketing materials provide unusually little concrete detail about its actual utility or roadmap beyond generic loyalty-reward language. Given the confirmed proxy risk, treat any BCX holding as carrying meaningfully elevated technical risk beyond typical market volatility.

Proxy contract: an upgradeable smart contract structure that lets a project's developers modify contract logic after deployment, offering flexibility but also centralization risk. Contract migration: the process of moving a token's functionality from one deployed smart contract to a newer one, which can leave old contract data no longer reflecting current token activity.
