Polkadot fell 5% today, pulling back to $1.14.
Polkadot (DOT) fell about 5% today, pulling back to $1.14, after briefly rising to $1.29 on October 10. Although Polkadot introduced a supply cap of 2.1 billion DOT and reduced token issuance, market demand for it still appears insufficient. The token began rebounding on October 9, rising from about $1.09 to $1.24, but fell again by about 7% on October 12.

Adam Back responds to Ledger co-founder's view on the AI ECDSA discovery
Coin World news: Adam Back responded to Ledger co-founder Nicolas Bacca's post on X, saying "checkmate satoshi," a humorous comment on Claude's revelation of the origins of the ECDSA curves. Claude discovered within less than half an hour the origins of the NIST P-192, P-224, P-256, P-384, and P-521 seeds, which did not come from any hash algorithm but were generated by the C library's lrand48 random number generator, with the seed being a Unix timestamp. This discovery reduced speculation that the mysterious NSA cryptographic seeds might hide a backdoor. Back further stated, "This is the NSA's fault, because they did not disclose the reproducible steps for generating the curves published by NIST." Bacca also said, "True, but it's still a good joke."

Self-proclaimed crypto king Aiden Pleterski was accused in court of misappropriating $16 million in investor funds.
A Canadian court heard evidence that Aiden Pleterski, who calls himself the Crypto King, misappropriated approximately $16 million of investor funds for personal expenses. He has pleaded not guilty to criminal charges, and the case is still being heard. A forensic accountant said Pleterski received tens of millions of dollars from investors, but most of the funds were not used in trading accounts and were instead spent on expensive vehicles, travel, and other personal expenses. According to the review, about $36.3 million was collected from investors during the review period, and prosecutors argue that these transactions misled clients about how their funds were handled. The case has drawn attention because Pleterski was previously the victim of a kidnapping. The jury will decide whether the evidence presented constitutes criminal misconduct.
