The only pyramid scheme I knew exists in religion and schools, bitcoin is far different from these two, no cap..
If Bitcoin is a proof of stake project I would have supported you, but I have to exchange my electricity power to get some BTC, something that grows in value over the years? Tell me how this is ponzi please, a ponzi that failed to die when no one is giving the any attention, a ponzi that failed to die when powerful centralised leaders are talking trash about it, bro you need some explanation to do.
There is no single traces that Bitcoin is ponzi, this currency benefits the new grabbers/buyers, it is all in the chart mate, every freaking four years this things adds more value like no other, the utility does what it was intended perfectly well.
