Why Blockchainjoin is on the register
Blockchainjoin, at blockchainjoin.com, calls itself simply “Blockchain” and sells USDC “savings” paying 0.7% to 2.7% interest per day on flexible deposits and up to 11% per day on fixed-term plans. The site will not run in a normal browser; it tells visitors to open it inside a crypto wallet app, the method used by wallet-draining “liquidity mining” schemes. Its payout feed shows wallet addresses containing letters no Ethereum address can contain. It names no company, address or regulator. Therefore, Blockchainjoin is a scam.
If you have money with this broker
- Stop sending funds. Do not pay any further “fees”, “taxes” or “verification” charges to release a withdrawal — this is a common secondary scam.
- Preserve evidence. Save transaction IDs, wallet addresses, chat logs, and every screenshot before the account is closed.
- Report it. Notify your bank/exchange and your national financial regulator so the activity is on record.
- Get guidance. Tell us what happened and we will point you toward the right next step. We are a free public registry — we never charge any fees.
