Why hasn't my Bitcoin payment posted?

We monitor every Bitcoin address created in our checkout. When an address receives it's first payment, credit or selected options are automatically provided to the correct user or ad. For this reason, the vast majority of delays are caused by external wallet services or user error. It's extremely rare that there's a blip in our software. Here are the most common issues: 

1. Wallet delays: Coinbase and other popular services have payment queues, and payments can be delayed on their end. In Coinbase, this is labeled as a 'Pending Payment'. There's nothing that can be done except for you to be patient and wait. We don't provide credit or renewals until payment hits one of our addresses. 
2. Wrong Currency Sent: We still get people sending Bitcoin Cash (BCH) on occasion. If you send BCH, the transaction is lost forever and we will not provide credit for this. Every cryptocurrency runs on it's own unique network, so payments cannot cross over from one currency to another. BCH shares the same format as Bitcoin (BTC) addresses, but they are owned by a completely different party. 
3. Paying the same address twice: When our Bitcoin addresses are used once, they go dormant. This is common practice to ensure anonymity and for payment tracking purposes. If you pay the same address from our checkout twice, credit will not be automatically issued.
