Worldcoin Conference "At Last" - April 30, 2025
The Worldcoin conference "At Last" is scheduled for April 30, 2025, at 5:45 PM (Brasilia time). The event will be led by Sam Altman, CEO of OpenAI, and Alex Blania, CEO of Tools for Humanity, with the promise of significant announcements about the future of Worldcoin, including updates on World ID, World App, and possible integrations with artificial intelligence and social platforms.
What to expect from the "At Last" conference
Expectations surrounding the event are high, especially due to rumors that OpenAI may announce a new social platform that will use the WLD token as its native currency. This possible integration between digital identity and AI could significantly boost the adoption and utility of the token.

Can the Cryptocurrency $TRUMP Rise Again?
The cryptocurrency $TRUMP , associated with Donald Trump, is a memecoin, a type of digital asset known for its high volatility and dependence on factors such as popularity, speculation, and market sentiment, more than solid economic fundamentals. Whether it can rise again depends on various unpredictable variables, especially in the current context, in April 2025.
Since its launch in January 2025, TRUMP has had a trajectory marked by impressive peaks — such as a valuation increase of over 28,000% shortly after the announcement, reaching a market value of $14.6 billion — and significant drops, such as losing two-thirds of that value in just a few weeks. In March 2025, its price was around $9.33, according to some sources, reflecting stabilization at much lower levels than its peak. This volatility is typical of memecoins, which often follow waves of hype and then retreat when the enthusiasm wanes.

CVM prohibits sale of Eike Batista's cryptocurrency.
On April 3, 2025, the Securities and Exchange Commission (CVM) prohibited the sale of the cryptocurrency $EIKE, launched by businessman Eike Batista, to Brazilians. The decision was made because the agency classified the token as a security, requiring registration and authorization for offering in Brazil, which was not complied with.
The CVM ordered the immediate suspension of the offering to the public residing in the country, under the penalty of a daily fine of R$ 100,000 in case of non-compliance. The measure reflects the CVM's analysis that the project, linked to the production of a "supercane" for sustainable fuels, was being promoted irregularly in the Brazilian market.

Bitcoin (BTC) fell sharply following President Donald Trump's announcement of a tariff package against dozens of countries, returning to the level of US$ 82 million. Previously, the cryptocurrency had risen and reached US$ 87 million, but was unable to maintain the optimism.
The tariffs, although less aggressive than expected, create a scenario of unpredictability and insecurity, which is likely to keep prices volatile in the short term. Trump announced a minimum tariff of 10% for all exporters to the U.S. and additional fees for about 60 nations with significant trade imbalances.
Ben Kurland, CEO of DYOR, stated that markets are likely to decline in the short term due to policy-driven volatility, not the tariffs themselves. Additionally, other cryptocurrencies also recorded negative performances, such as Solana, which lost 8%, and Dogecoin and Cardano, which each lost more than 5%. #Trump #bitcoin

"Bolsonaro Coin" (BSN22): token created in 2021 by supporters of Jair Bolsonaro.
Launched on the Binance Smart Chain, the project was conceived as an initiative to support his candidacy for reelection in 2022, in addition to pursuing social and humanitarian purposes. According to the developers, 75% of the 60 million units of the token would be allocated to charitable causes indicated by the then-president, provided they were nonprofit entities. The token was listed on the NFXTrade exchange and also traded on PancakeSwap.
In the first 10 days of trading, the Bolsonaro Coin appreciated by 20%, reflecting a surprising initial demand, as reported by the creators. They claimed to have intervened to stabilize the price, aiming for sustainable appreciation. Despite carrying 'Coin' in the name, it is not a traditional cryptocurrency for transactions but rather a collectible NFT, tradable for other digital currencies or fiat money. In June 2021, its value was around R$ 1.22 (equivalent to 0.00000650 BTC), but only 115 digital wallets held it, according to BscScan.

Dilma Coin: the "dead coin" inspired by Dilma Rousseff.
Dilma Coin is considered one of the first Brazilian cryptocurrencies, launched in 2014 as a satire inspired by then-president of Brazil, Dilma Rousseff. Announced on the Bitcointalk forum on March 23, 2014, it was presented as "the president's coin" and had an official website (now inactive). The project emerged in a context of protests in Brazil during the World Cup, when Dilma was the target of criticism and insults, which apparently motivated the creation of this cryptocurrency as a joke or experiment.

The Patriota Coin ($PATRIOTA), launched in January 2025 by supporters of Jair Bolsonaro, is a memecoin on the Solana network that seeks to capitalize on the political engagement of Bolsonaro supporters, inspired by the success of cryptocurrencies like $TRUMP, associated with Donald Trump. There is no official link with Bolsonaro, despite using his image and conservative aesthetic. As of April 1, 2025, here is the most recent overview based on available information:
In the beginning, the Patriota Coin experienced a surge of interest. In its first 24 hours, it attracted about 1,200 investors and raised $390,000 (approximately R$2.3 million at the time's exchange rate), with an impressive appreciation of over 9,400%, rising from $0.0001578 to a peak of $0.015. However, this high was followed by a significant drop. In just a few days, it lost more than 50% of its value, trading at $0.0004602 on January 24, with a market capitalization of about R$2.7 million. Since then, volatility has continued to mark its trajectory.

How Are Cryptocurrencies Created?
Cryptocurrencies are created through processes that combine technology, cryptography, and rules defined in software codes, usually based on blockchain or other forms of distributed ledger. The exact method depends on the type of cryptocurrency and its purpose, but I will explain the main creation pathways clearly:
Mining (Proof of Work - PoW)
- How it works: New coins are created as rewards for "miners" who use computing power to solve complex mathematical problems. These problems validate transactions and add blocks to the blockchain.

Who are the "SARDINES" in the world of cryptocurrencies?
In the context of cryptocurrencies, "sardines" is a term used to describe small investors, usually individuals who hold relatively modest amounts of crypto assets. These investors have less capital and influence in the market compared to the "whales," who are the large holders of cryptocurrencies, such as institutions or individuals with vast quantities of digital assets.
The metaphor comes from the animal world: just as sardines are small fish that swim in schools and can be easy prey for larger predators, in the crypto market sardines are seen as vulnerable to the movements of whales. For example, a whale can sell or buy large volumes of a cryptocurrency, causing price fluctuations that affect the sardines, who often react emotionally, buying during highs out of fear of missing out (FOMO) or selling during lows out of panic.

Flamengo in the cryptocurrency market?
Flamengo, one of the largest football clubs in Brazil, has shown interest in entering the cryptocurrency market as part of a strategy to diversify its revenue sources and further engage its huge fan base. This move reflects a growing trend among global sports clubs that have been exploring crypto assets, especially through 'fan tokens', to strengthen their brand and offer exclusive experiences to fans.
The club has already launched the Flamengo Fan Token (MENGO), in partnership with the platform Socios.com, which uses the Chiliz blockchain. The $MENGO token was officially introduced in October 2021, allowing fans to participate in club decisions, such as choosing uniform details or warm-up songs, in addition to accessing exclusive rewards. The initiative aims not only to generate revenue — with estimates of around R$ 145 million over five years, according to information released at the time — but also to bring Flamengo closer to its global fan base in an innovative way.

Founder of Binance charges R$ 720 in cryptocurrencies to receive messages from followers.
Changpeng Zhao, former CEO and founder of Binance, is truly trying an innovative approach to manage his interaction with the crypto community after his release from prison in 2024. By adopting the ReachMe platform and charging 0.2 BNB (approximately US$ 125) per message, he aims to filter the massive volume of contacts he receives daily, limiting interactions to ten messages per day. This strategy, which he calls "Pay to Reach", reflects an attempt to balance accessibility with the need to avoid trivial or irrelevant messages, such as those he mentioned ("check out this meme cryptocurrency" or "how was your dinner?").
The idea of using cryptocurrencies as a form of payment and adjusting the price based on demand shows an adaptation to the market he helped shape, in addition to reinforcing his vision that traditional platforms, such as LinkedIn and X, suffer from very low entry barriers, generating noise instead of productive conversations. The fact that he offers a five-day response time, with partial refunds in case of non-compliance, also adds an element of accountability to the model. #Binance #ChangpengZhao
