Blockchair only provides blockchain search and analytics services. We are neither a blockchain wallet, nor the official Bitcoin Cash support, so there is nothing we can do to help you with your payments.
Q1: Why does it take so long before my cryptocurrency transaction is processed?
A1: Miners process transactions based on the transaction fee that is attached to a transaction. If your transaction fee is low, it might take some time before the transaction is included in a block. Some wallets support functionality to increase the transaction fee. Please reach out to your wallet or exchange to find out what you can do to make your transaction process faster. We cannot do anything to process your transaction faster.
Q2: Can I reverse a cryptocurrency transaction that was sent incorrectly?
A2: Irreversibility is one of the fundamental properties of cryptocurrency. If you want to know if there is still a chance to get your funds back, please contact your wallet or exchange. Blockchair is not a bank, just a search engine for blockchains. We can not reverse transactions in public blockchains. No one can!
Q3: Why do I see my money on Blockchair and how come Blockchair has my money?
A3: Blockchain is a public distributed database of which anyone can make a copy. Your cryptocurrency transactions and address balance are also stored here. At Blockchair we provide insight into data that is stored in blockchains. We offer ways to find, sort and filter data that is stored in blockchains, so you can easily check your address balance and transaction history. We do not provide wallet services and do not process transactions.
Q4: I sent Bitcoin to a Bitcoin Cash/Bitcoin SV address (or vice versa). Is it possible to retrieve my funds?
A4: If you sent Bitcoin Cash or Bitcoin SV to a Bitcoin Segwit-address (an address starting with a 3), it's not possible to recover the funds. Otherwise, the answer depends on who is the recipient of the transaction:
- You: your private keys (and passphrases) for Bitcoin wallets are valid for Bitcoin Cash and Bitcoin SV wallets and vice versa, so you just need to export and import your keys (passphrases). Please contact your wallet if you need help with this.
- An exchange (Bittrex, Poloniex, Binance, etc.): in this case, you should contact the exchange support.
- Your friend or colleague: you could ask the recipient to install the second wallet and explain that he has to import his private key into that wallet. Please contact your wallet if you need help with this.
Q5: Is it possible to retrieve Ethereum that I deposited to an ERC20 address (or vice versa)?
A5: If you made a deposit on an exchange and sent Ethereum to an ERC20 address (or vice versa), please contact the exchange to find out if they can retrieve your funds. If you sent Ethereum to an ERC20 address (or vice versa) that you control, you should be able to retrieve the funds. We cannot help you with this, your wallet can explain how to do this.
Q6: What does the ‘Bitcoin halving’ mean?
A6: In public blockchain networks, miners verify transactions in blocks and are rewarded with transaction fees and newly minted coins. In Bitcoin and several other blockchains, the number of newly minted coins per block is cut in half every 4 years, so inflation is limited. In Bitcoin networks, the reward started with 50 BTC per block, which already has been halved to 12.5 BTC per block. Soon, this will become 6.25 BTC per block.
