Every bitcoin transaction that's sent flows into what's called the mempool (short for memory pool) before it can be confirmed by miners. When there's a dramatic spike in transaction activity, the mempool can become congested because so many transactions are waiting to be included in the next block.

Bitcoin users across the network may notice their transactions sit as unconfirmed or pending for a longer period of time, and we understand this can cause users to be concerned about the status of their funds.


Sometimes, if you don’t see the coins in your wallet, it just needs to be refreshed by closing out of the app and opening it back up again.  Some wallets will not show the coins until the transaction has been confirmed on the blockchain, which typically takes about 10-20 minutes, unless the bitcoin network is slow to confirm. 

If you are concerned about your coins not being sent, please check your transaction on the network, enter your wallet address into blockexplorer.com for instant check.

Sometimes the Bitcoin network gets very busy. It can take up to 24 hours to receive confirmations

Block Explorers provide a visually appealing and intuitive way to navigate the bitcoin blockchain, and was created as a way for anyone to study bitcoin transactions, along with a variety of helpful charts and statistics about activity on the network.
