Bitcoin is not a ponzi scheme

Wikipedia defines a ponzi scheme in the following way:

"A Ponzi scheme is a fraudulent investment operation where the operator, an individual or organization, pays returns to its investors from new capital paid to the operators by new investors, rather than from profit earned by the operator. Operators of Ponzi schemes usually entice new investors by offering higher returns than other investments, in the form of short-term returns that are either abnormally high or unusually consistent. The perpetuation of the high returns requires an ever-increasing flow of money from new investors to sustain the scheme."

Now let's see if that fits bitcoin:
-Does bitcoin have central authority? No. YES, instead of banks, bitcoin controlled by mining companies and rich criminals, Satoshi HD Moore Roger Ver knightmb Mark Karpeles Loaded FBI..
-Does bitcoin pay returns to its investors? No. YES, bitcoin works like a pyramids scheme, bitcoiners cheat greater fool to buy so bitcoiners can sell their bags at higher price (a promise given by dream)
-Does bitcoin require an ever increasing flow of money to sustain it? No. YES, mining and fees charged by exchangers cost $$$

Bitcoin is not a Ponzi scheme. It's a true innovation in computer science and solves a well known problem called the Byzantine Generals problem.

It's a new type of monetary system based on mathematics and rare numbers. That's why it's a game changer. That's why we see 5-10 million investments to bitcoin startups every week. It has nothing to do with a Ponzi scheme.

False.  Allow me to quote Bitcoin Wiki:
"In a Ponzi Scheme, the founders persuade investors that they’ll profit. Bitcoin does not make such a guarantee."-- https://en.bitcoin.it/wiki/Myths#It.27s_a_giant_ponzi_scheme
