What is Bitcoin Tower?
Bitcoin Tower is an experiment in modern capitalism and conspicuous consumption. The only rule here is the person who pays the most tops the tower. After that, all the previous levels are sorted in descending order. You can even attach a message to say whatever you want or advertise something!
What does topping the tower do? What are the 'previous levels'? Very little is spelled out on your website, seems like it's just a cash grab.
