Are there any plans to move onto a new card provider since Wavecrest has essentially said no more customers outside of the EU? Most of your business imo are actually going to come from countries outside of the EU zone, like America, NZ, AU, etc.
If you can provide a produuct that works worldwide i think that you're going to find a lot of success.
Right now, most card providers don't have a working product outside of the EU. You can boost your business here.
Why dont you use a mail forwarding service in a country they ship to? You cant get the card fully verified with alternative user data but you can order more then one card and use it till the limits are reached and then use another one.
