BitPay, Cryptopsy, and Bitwala have all had their cards suspended as of 5 January, meaning they cannot be used to pay for goods on the high street.
Visa said in a statement: “We can confirm that WaveCrest’s Visa membership is being terminated due to non-compliance with our operating rules. All WaveCrest-issued Visa card programmes will be closed as a result.
“The termination of WaveCrest’s Visa membership does not affect other Visa issuers’ card programmes, including those using fiat funds converted from cryptocurrency.[1]

1. Are you using Bitcoin pre-paid cards?
2. Do you think Visa locks will effect bitcoin?
It doesn't has a strong impact on bitcoin.
The companies that issued visa debit cards that are being loaded with bitcoins usually charged an huge fee for that, what made it really unprofitable to use the bitcoins through the debit card.
I don't believe that they had many users, but it's maybe a sign that regulators are starting to look into crypto market and may attempt to regulate it, a thing that will damage the market at the long run.
