Hm no, Bitcoin is not a gamble on a Ponzi Scheme, not in the slightest. I think I know what you mean and that I shouldn't take you literally here (correct me if I am wrong), but Bitcoin offers something real and the surplus value inherent in Bitcoin has not yet been captured by the market, which means that it has plenty potential to grow. Money is always an incentive and I won't deny that, but money is as much an incentive when you invest in a sound real estate as it is when you invest in a sound monetary alternative. If you want to, you could say that investing per se involves an element of gambling, but to me that sounds too superficial and I am sure that's not the the conversation you intend to have.

In gambling people sometimes seek a way to waste time literally. To forget the present and do something that keeps them excited because normal life can't do the job. A Bitcoin investor isn't excited 24/7 I think. It is an exciting topic, but to reach the gambling effect I would have to play "Up or Down" on some gambling site, hoping that my bet on "Up" within the next 30 seconds hits. That's not how I look at Bitcoin.
