When you make a crypto deposit, you'll often see a "confirmation" count on the blockchain. A confirmation means a new block has been added that includes your transaction. Each block makes the deposit harder to reverse, which is why crypto services track them.
The number of confirmations required varies depending on the coin and the network you're sending on. In most cases, the confirmations required don't prevent the funds from showing up in your Cloudbet account and being used.
