I have contributed to the TenX token sale, so they will send me a special card (I think it is going to take until September for me to receive it).
I haven't used any of the others, but I really like how the TenX team is handling their project. They are frequently posting development updates in their blog and I think they are very transparent and have a very good governance concerning funds raised and tokens held by the team.
I can soon give you my impressions after I use my card for the first time .
Just wondering if you have actually received the card from them that you have been patiently waiting for. Are you residing inside the EU or somewhere else as if it's somewhere else you may be in for a really really long wait.
