Now I think that only Wirex has a properly working card.
To my opinion there are many users interested in crypto debit cards services but still there are no new providers appearing at the market. What do you think that is reason for that and will that change in the future?
There are probably more debit cards available and Wirex is definitely not the only one, but you're right on the issue.
The problem isn't a lack of bitcoin debit card providers per se, though. There is a lack of anonymous debit cards that could previously be used without any verification, and now, every single provider requires you to provide at least basic ID before you are able to use their services.
There isn't really nothing that could be done though, because this stems from a) the tightening of regulations which increase barriers for entry for prospective providers and b) the tightening of policies from corporations like Wavecrest in the past that has limited certain services from being able to be provided. You just got to make do with what you've got, or simply convert your BTC into fiat every now and then.
The problem is not the lack of debit card providers per se, there is a lack of debit card that can be used without any verification. Ideally, each provider must provide an ID to use the services. This issue is also solvable if emerging companies consider that an ecosystem would make this process easier. Within the ecosystem, a franchise model must provide the banking-like service to solve the liquidity problem in addition to being who supports the debit card issuance and security in partnership with something akin to Visa or MasterCard.
