The zero bill bank is one of my favorite project that I've ever seen in this crypto world. They are really working hard to make it better each time we meet them at their events or conferences. The communication level has been great so far. We had some problems but everything got fixed fast and no worries about anything anymore. Keep up your good job guys! Nothing yet. It's very new for us so there was nothing to dislike for now. Just keep growing and you will see how people love you more every day. Try to be honest always because you never know who might need help from you someday. Zero Bill Bank is helping us to get rid of all our bills and invoices. So far so good and we don't think there would be any problem if they continue doing what they're doing.
