Bitcoin requires 2-3 confirmations (20-30 minutes) before the exchange proceeds to ensure transaction security.
Bitcoin transaction confirmation speed depends on the current blockchain network congestion.
We use SegWit Bitcoin addresses for faster and cheaper transactions. Contact support if your wallet doesn't support SegWit.
Bitcoin is the first decentralized cryptocurrency and remains the most popular digital asset. Created in 2009 by an anonymous person or group known as Satoshi Nakamoto, Bitcoin introduced blockchain technology to the world and sparked the cryptocurrency revolution. Its dominance index over other cryptocurrencies typically ranges from 30% to 80%.
Bitcoin operates on a decentralized peer-to-peer network with no central authority. It has a fixed supply of 21 million coins, making it deflationary by design. Transactions are verified through a process called mining, which uses the proof-of-work consensus mechanism. The Bitcoin halving, which occurs approximately every four years, reduces the rate at which new bitcoins are created.
Most likely your wallet does not support sending to SegWit Bitcoin addresses. We use SegWit because with this technology, transactions are included in blocks faster and the miner's fee is much lower, making transactions faster and cheaper.
If your wallet doesn't support sending to SegWit addresses, we recommend changing your Bitcoin wallet as it uses outdated technology. You can also contact our support to change the wallet address to a standard one in real time.
While it's impossible to calculate confirmation time with complete accuracy, you can check statistics from services like Blockchain.com to estimate when your transaction will be included in a block based on the fee.
Each Bitcoin block contains approximately 2,500 transactions with an average block time of 10 minutes. The number of confirmations increases as new blocks are added to the blockchain.
