What do you guys think?
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
