Yes, I fully echo your opinion.

Fraudulent transactions charged to prepaid / debit cards:
- The cardholder's money is already deducted, and shall be only returned to the cardholders, after the bank or fintech completes the investigation of the fraudulent transactions, which can take several weeks. That equals several weeks of anxiety, restlessness and confusion, endured by cardholders.
- The bank or fintech does not pay much attention to such fraudulent transactions (less urgent in the priority list of bank or fintech), because it is not the money of bank or fintech, being deducted.
- All risks fall on the cardholders, instead of the bank or fintech.
Fraudulent transactions charged to credit cards:
- The cardholders need not pay any money, because as soon as the cardholders reports the fraudulent transactions to the bank or fintech, the bank or fintech immediately flags / withholds the floating fraudulent transactions, from being settled by fraudulent merchants.
- The bank or fintech is more committed and deploys much greater resources in solving the issue of fraudulent transactions, because the money of the bank or fintech is at risk being claimed by fraudulent merchants. Note that the credit limit of the credit cards is some sort of short-term loan offered by the bank or fintech, to the cardholders.
- Almost all risks fall on the bank or fintech, instead of the cardholders, as long as the cardholders immediately reports that the fraudulent transactions are performed beyond the knowledge of the cardholder.
In short, for unknown transactions, it is better for us the cardholders to use credit cards, instead of prepaid / debit cards, because credit cards will offer better protection to the cardholders.
Well, it is a well-known fact that BigPay Prepaid MasterCard is a prepaid card. So, we have to accept the risk of using BigPay Prepaid MasterCard, since we want to reap the benefits of using BigPay Prepaid MasterCard.
Thank you so much to
cybpsych, and many other experts here in this wonderful subforum whom I gain tons of useful knowledge.

That's one of my main concern from Day 1, and there's really no urgency in BP investigating fraud cases compared to banks.
