I do wonder which is really better between using these two types of digital payment system for both sides of transactions as to:
1. speed;
2. reliability; and
3. security.
I think it depends on which country you have belong.
For first world country either bitcoin or debit card were still okay. Most people in europe have master card so the everyday transaction when they bought goods were very smooth and fast.
For third world country. The everyday transactions were slow and tiring because most people do not have a debit card they used cash when buying goods.
For this reason bitcoins were better in third world countries because people could pay through mobile online transaction. Internet and cellphone today is necessary to everyone so online transaction was not a problem anymore. However the problem was that not all stores in third world country accept bitcoins.
In terms of speed and reliability both bitcoins and debit cards were the same. However in security I believed bitcoins was better compare to debit card.😁
