you can still Google a lot of information. I do not advise you to invest in PRIZM
The first article is paid. Have ever heard such an expression: "Engaged media"? This is just the case. Besides, the article is not english. That resource ("forklog") was quite decent and trust until in 2018 it was attacked by SBU (Security Service of Ukraine). SBU hacked their Bitcoin wallets and since then "forklog" is biased.
The second article is also not english. Moreover it is very old article. Events that were described by this article are dated approximately august 2018. Since then, 2 years have passed. The Prizm successfully migrated to new blockchain. All the holders made profit 4X then the price almost had returned to its previous value. The profit was made due Prizm staking (so-called "Paramining"). Prizm staking percent was 20% per month, very high at that time.
The third article none english again! If you want to talk to english speaking people then why you don't give your provements in english? Besides, they don't tell us about Prizm. They say about its developer's biography. That is just like if you, instead of talking about Tesla achievements, would telling Elon Musk life story.
⚠️ By the way as you can see there is no even a single fact of scam associated with Prizm. You may, of course, manipulate the facts. But doing so you may also say that every medicines made by Bayer company are addicts' drug, narcotics, because of the Bayer exactly was the one who invented Heroin.
