Most of these things listed above are NOT pyramid schemes, unless they are causing value to float to the top without any reciprocating value being transferred below. The only way that value gets transferred lower down the pyramid is to find more suckers below. None of these listed items are pyramid schemes, unless they are designed as such. Bitcoin is also NOT a pyramid scheme b/c there are tangible assets, including an infrastructure and a network and continued investments in side businesses.... NO need to explain further at the moment b/c these pyramid scheme/ponzi arguments are totally attempting to simplify bitcoin into something that it is NOT and playing upon ignorance.
you know a sucker like you and me who made Satoshis and the winklevoss and ...... coins more valuable, the last ones in the pyramid will have 0 vale when Bitcoin collapse (it will collapse at one point in the future).
and it is a pyramid, because at the start people created the coin of nothing, well, except the few cents consumed by the processor on power, they hoarded and pumped the value so more suckers jumped in through time. I am one of them BTW.
well yea, it is genius that it solved a mathematical problem....same like tampon did solve a problem if you ask a woman.
