BlockBeats news, September 28: Yesterday, the altcoin Quant (QNT), which had already held a top position on the gainers list for several consecutive days, was completely ignited by a tweet. Analyst Jan Nieuwenhuijs, citing his 2013 tweet calling for buying Bitcoin, posted a new tweet saying, "Today I suggest everyone buy at least 1 QNT. Risk: losing $120, potential gain: $10,000."The tweet was widely spread, and QNT surged 145% in a single day, reaching a high of $373, soaring 430% in 4 days. As of press time, QNT has pulled back nearly 30% from its high, now trading at $253, corresponding to a market cap of $3.15 billion.Historical data shows that Jan Nieuwenhuijs did not suddenly decide to call for buying QNT. He first began paying attention to and mentioning QNT in June 2023. At that time, the Bank for International Settlements (BIS) released a report on the "unified ledger," and Quant also happened to announce cooperation with the BIS and the Bank of England on Project Rosalind. From then on, he began tweeting, linking Quant's Overledger with this "unified ledger."On the news front, Quant Network announced on September 24 that it had reached a cooperation with The Clearing House (TCH), a major U.S. bank clearing institution, to bring on-chain programmable money to the U.S. market. Quant will provide an interoperability layer to enable tokenized deposits to circulate freely within the regulated banking system. This cooperation is an extension of its related work in the UK, Europe, and other regions.In response, Jan Nieuwenhuijs said he expects another official cooperation to be announced by Quant (QNT) in the coming months, possibly Project Agora. Agora is a multi-currency shared platform for wholesale cross-border payments, with participating countries including France, Japan, South Korea, Mexico, Switzerland, the UK, and the U.S. Participants also include HSBC, Citi, JPMorgan, Santander, Deutsche Bank, the Bank for International Settlements (BIS), SWIFT, Visa, and Mastercard.It is reported that Jan Nieuwenhuijs is an independent Dutch gold analyst who, under the pseudonym Koos Jansen, was the first to expose that China's gold demand was severely underestimated by the West and that central banks were secretly stockpiling gold, thereby becoming famous in the international gold circle. In 2013, he posted a tweet recommending buying Bitcoin: "I suggest everyone buy at least 1 Bitcoin. Risk: losing $300, potential gain: $10,000."
