Hi, It's Unicorn

Bitcoin, as a general transaction payment method is not common. The reason is that it takes a long time to wait for the transaction confirmation process. It may take 10 to 30 minutes or more time. Compared with other payment method, efficiency is one of the shortcomings of Bitcoin as a general transaction payment. 

In addition, the transaction processing volume per second of the Bitcoin network is very different from Visa, Mastercard, Paypal and other mobile payments. The average transaction processing volume per second is only about 5 transactions per second, which cannot carry the global payment volume, unless Bitcoin has a significant improvement in throughput. With technological breakthroughs, processing the number of transactions is still the biggest challenge of Bitcoin.

However, the pro of Bitcoin as a payment is the international remittance of cross-border payments, which is not subject to geographic restrictions. For instance, your local fiat currency may not be supported when you need to buy foreign goods. If you use Visa or Mastercard, you need to pay a handling fee. At this moment, if the merchant can accept Bitcoin as a payment, this problem can be solved. You can choose BTC as the payment at the merchant which supports BTC payment, and follow the instructions to complete the payment.

The basic Bitcoin payment process of merchant is as follows:

When the buyer chooses Bitcoin as the payment, the merchant will convert the value of the product into Bitcoins, and provide the designated Bitcoin wallet address. The buyer transfers bitcoins to the designated wallet address, and the merchant receives Bitcoin, will ship and complete the transaction.
