No need for examples. The fact is that when you invest in the bitcoin system and get the record of your investment that shows how many shares(BTCs) in this system you hold, the system will never return even a dime worth of your investment. Which is why you're forced to dump your worthless shares to new investors. These new ones must also dump them. And so on. When there's no one left to dump them on, the whole system collapses. And that's literally how all investment scams operate. The bitcoin system is just a scheme for dumping the worthless shares from one investors to another and recording how many shares a particular investor has or has had.
Every thing you said now is repeatition of what you said in other of your response.from what you are explaining are you trying to tell the world that Bitcoin system is worthless and valueless. From this sentence i can sense that you labelled bitcoin as a scam zone, if you want agitation and condemnation of bitcoin, try to come up with good point with good explanation not repeating them in several occasions
