It appears to be a common habit for morons and noobs to declare anything a Ponzi they don't understand or somehow lost money on (usually through their own stupidity).
It is annoying because it acts as if words don't have meanings. A Ponzi is a very specific kind of investment scam or (more recently) a kind of gambling game open about its intentions. BTC is simply not a Ponzi by any rational definition of the term (although arguably BTC is somewhat prone to being used in Ponzis but pretty much any currency or commodity could in theory be used in a Ponzi).
No, Bitcoin can reasonably be classified as a pyramid scheme though.
Not really, although whereas unlike a Ponzi, which Bitcoin is nothing like, it is merely almost, but not entirely unlike a pyramid scheme. And again, BTC can be
used in a pyramid scheme, like bitcoinpyramid, but that is entirely different from
being a pyramid scheme.
No, it's exactly like a pyramid scheme. The founders availed themselves for very little effort millions of bitcoins, these same coins are now only available if purchased or mined at a slow rate with expensive dedicated hardware, and as the difficult ramps up even the means to mine with dedicated harware will be beyond anyone without the means to drop 100k on dedicated hardware.
Under that definition, any company is a pyramid scheme in its beginning. (which is obviously false)
You clearly don't understand what a pyramid scheme is.
So the masseuse in Google was part of the pyramid scheme because she got paid with shares in the beginning of the company? Employees getting paid in Google with shares were risking their neck because there weren't having a salary, and there wasn't anything reassuring that it would be such a commercial success. They didn't even had a business plan.
Today everyone who lent their time to Google, they are billonaires. Even the masseuse.
The same with bitcoins, in the beginning nobody gave a damn about this project and it was just experimental.
Nobody would have expected to grow so fast and to have such a relevance.
So those who put their necks and time in this project ended up being rewarded for trusting in it from the very beginning.
So please, study better your terminologies and get more life experience.
