Ser, the term "Ponzi" was merely stigmatized because the originator was a scammer. But TECHNICALLY it describes how in order to exit the system with some profit, NEW MONEY must enter that system. Do you understand?
Bitcoin is a naturally-occurring Ponzi LIKE Gold, NOT a scam like those Ponzi Schemes that has a nefarious entity on top. There's a difference, ser.

Maybe best to avoid any misleading information towards name calling of bitcoin you or other people should stop calling it as Ponzi since that word give bad impression to people since it associate with frauds or anything illegal that you can imagine.
Just call bitcoin as bitcoin and don't use other term to describe it since you don't know what came up on the people's mind especially when you call it a Ponzi like asset. This is also the reason why I don't call bitcoin as crypto since it mislead people again to other scam project saying that they are the next bitcoin. To many confusion spreading around and to many newbies in the scene so to avoid giving problems to those people we should call bitcoin its known name and don't compare it with other asset.
Yeah you are right if one don't call Bitcoin by it's name you may mislead some newbies, I know someone who believed that all other crypto coin are also known as Bitcoin which lead him to invest in a shitcoin and he lost his money, so we should always call Bitcoin by it's name to avoid complicating things.
Ponzi scheme has really made a lot of people lose there money and by the mention of the name Ponzi what comes to some people's mind is scam and Bitcoin should not be link to Ponzi as is a very different thing.
People should understand that there are newbies who don't engage in discussion here but often come on threads like this to learn about Bitcoin investment therefore everyone has to be careful concerning things they say so as not to mislead those newbies and give wrong impression to them about Bitcoin, he might not have called Bitcoin a Ponzi but relating it to that name alone is mislead and once those newbies learn that a high ranking member is relating Bitcoin to Ponzi then they'll think it has scam features on the long run, let's the guided and try as much as possible possible to pass the right informations while we discuss about the concept of Bitcoin investment, Bitcoin has nothing relating to Ponzi and if one invest on Bitcoin the right way and follow it concepts thereby using good methods then they'll benefit from it and even recover loses, expect for those who use it for trading despite being aware of the high risk factor.
