In Coinosh, for you to be able to spend Bitcoins that were just received, the transaction needs to receive a certain number of confirmations on the blockchain. This confirmation process verifies the validity of the transaction and ensures it is added to the Bitcoin network.

Typically, Coinosh requires 3 confirmations for a Bitcoin transaction before the received funds can be used for new transactions. Confirmations are obtained when miners on the Bitcoin network include the transaction in multiple blocks, securing its place in the blockchain.

The time it takes to receive these confirmations can vary depending on network congestion and the fee included with the transaction. On average, it may take around 30-40 minutes for a transaction to receive 3 confirmations.

You can track the confirmation status of your transaction within the Coinosh app or by using a public Bitcoin block explorer. Simply enter the transaction ID to view the current number of confirmations.

Once the transaction has received the required number of confirmations, you will be able to use the received Bitcoins for new transactions within Coinosh.
