Each block is found at a different rate depending on the blockchain.
For example, on the Bitcoin blockchain, a block is mined every 10 minutes on average, and LCX.com only credits Bitcoin deposits to a client’s account after 4 confirmations, which takes approximately 40 minutes.
However, sometimes it can take Bitcoin miners 30 or even 60 minutes to mine a single block (1 confirmation). LCX can’t control the time taken for these confirmations.
