Nope, it's not a scam and this isn't a game.
What ponzi is, when bitcoin goes to zero after going all time high. Well, did it go to zero? Actually yes, and it went zero from those people that don't even hold bitcoin.
They keep telling that bitcoin will go to zero but look at how much it went during the all time high and how much it is right now.
They are wrong if they think of the bitcoin system as a ponzi. They don't see bitcoin moving year after year when the bitcoin price is down like this they can't afford it.
Currently bitcoin is at a price of $ 20 thousand and will probably fall below $ 20 thousand again and that is an important moment for us to buy more.
It has fallen to $18k and $19k.
These people will only change to say that bitcoin is a ponzi when they own a bitcoin. They will understand the concept of it and the technology that it has because the value of money is on it.
But, we don't need to be thinking of them while we just keep on going because eventually, they'll be left behind when the bull comes again and the price increases.
