Cardano is a blockchain platform built on academic research that enables smart contracts and decentralized applications while using significantly less energy than traditional cryptocurrencies like Bitcoin.   What sets Cardano apart is its methodical, research-driven approach — every major feature is peer-reviewed by scientists and cryptographers before being added to the network. This careful process aims to create a more secure and stable foundation compared to platforms that prioritize speed over thorough testing. The platform's native cryptocurrency, ADA, is used to send money, pay transaction fees, and participate in network governance.  Cardano uses a proof-of-stake system to process transactions, which works differently from Bitcoin's mining approach. Instead of competing to solve complex puzzles, users can "stake" their ADA — essentially locking it up temporarily — to become validators who verify transactions. The system selects validators based on how much ADA they've staked and for how long, then rewards them with additional ADA for their participation. This approach uses far less energy than traditional mining while keeping the network secure. The platform also features a two-layer design that separates basic payment transactions from smart contract operations, allowing each function to be optimized independently for better performance.   ADA holders can earn staking rewards by locking up their tokens to help secure the network, vote on proposed changes to the platform, and use ADA for international money transfers with lower fees than traditional services.  Cardano was founded in 2017 by Charles Hoskinson, who previously helped create Ethereum. Hoskinson leads Input Output Global (IOG), the technology company that builds and maintains Cardano's core software. The ecosystem operates through three organizations: IOG handles technical development, the Cardano Foundation promotes adoption and standardization, and Emurgo helps businesses integrate blockchain technology into their operations. This structure distributes responsibilities across multiple groups rather than concentrating control in a single entity.   In February 2025, major asset manager Grayscale Investments filed to create an exchange-traded fund (ETF) for Cardano with the U.S. Securities and Exchange Commission, which would allow traditional investors to buy ADA through their regular brokerage accounts without needing to set up cryptocurrency wallets.Retry

Cardano

Cardano (ADA) is trending amidst widespread community alarm, with a dominant narrative of a 'rugpull' and declarations that 'crypto is dead' following significant price declines. Many holders are expressing extreme frustration, labeling the asset a 'scam' and criticizing its founder, with some urging a sell-off and a pivot to other assets like AI stocks or XRP, while a smaller contrarian group advocates buying the deep dip.

BlackRock Institutional Trust Company N.A. - iShares Silver Trust

iShares Silver Trust

iShares Silver Trust is trending as global market participants react to reports of soaring physical silver prices in Shanghai and impending Chinese export restrictions. The community is actively discussing a potential "silver squeeze," fueled by concerns over structural supply deficits and rising industrial demand from sectors like EVs and AI data centers. While many anticipate significant further upside and a re-rating of silver's value, some observers warn of potential near-term volatility after its rapid ascent.

Polkadot is a platform that allows diverse blockchains to transfer messages, including value, in a trust-free fashion; sharing their unique features while pooling their security. In brief, Polkadot is a scalable heterogeneous multi-chain technology.  Polkadot is heterogeneous because it is entirely flexible and makes no assumption about the nature or structure of the chains in the network. Even non-blockchain systems or data structures can become parachains if they fulfill a set of criteria.  Polkadot may be considered equivalent to a set of independent chains (e.g. a set containing Ethereum, Ethereum Classic, Namecoin and Bitcoin) except with important additions: pooled security and trust-free interchain transactability.  Many of the native parachains of Polkadot will be written using a Polkadot Runtime Environment SDK (e.g. Parity Technologies' Substrate).

Polkadot

Polkadot (DOT) is generating buzz as its DAO recently capped the token supply at 2.1 billion with future emission halvings, fundamentally altering its tokenomics towards scarcity. This significant shift, combined with ongoing Polkadot 2.0 upgrades enhancing elastic scaling, is sparking active community discussion about the network's long-term potential and attracting renewed interest from both developers and institutional entities in the interoperable Web3 space.

Coupang Inc - Ordinary Shares - Class A

Coupang Inc 

Coupang is trending due to a massive data breach affecting millions of South Korean users, sparking intense regulatory scrutiny and significant public backlash against the company's leadership. The community is sharply divided between those fearing severe government penalties and consumer boycotts, and others who see the recent sell-off as an oversold buying opportunity given Coupang's entrenched e-commerce dominance in the region.

Ripple is the catchall name for the cryptocurrency platform, the transactional protocol for which is actually XRP, in the same fashion as Ethereum is the name for the platform that facilitates trades in Ether. Like other cryptocurrencies, Ripple is built atop the idea of a distributed ledger network which requires various parties to participate in validating transactions, rather than any singular centralized authority. That facilitates transactions all over the world, and transfer fees are far cheaper than the likes of bitcoin. Unlike other cryptocurrencies, XRP transfers are effectively immediate, requiring no typical confirmation time.  Ripple was originally founded by a single company, Ripple Labs, and continues to be backed by it, rather than the larger network of developers that continue bitcoin’s development. It also doesn’t have a fluctuating amount of its currency in existence. Where bitcoin has a continually growing pool with an eventual maximum, and Ethereum theoretically has no limit, Ripple was created with all of its 100 billion XRP tokens right out of the gate. That number is maintained with no mining and most of the tokens are owned and held by Ripple Labs itself — around 60 billion at the latest count.  Even at the recently reduced value of around half a dollar per XRP, that means Ripple Labs is currently sitting on around $20 billion worth of the cryptocurrency (note: Ripple’s price crashed hard recently, and may be worth far less than $60 billion by time you read this). It holds 55 billion XRP in an escrow account, which allows it to sell up to a billion per month if it so chooses in order to fund new projects and acquisitions. Selling such an amount would likely have a drastic effect on the cryptocurrency’s value, and isn’t something Ripple Labs plans to do anytime soon.  In actuality, Ripple Labs is looking to leverage the technology behind XRP to allow for faster banking transactions around the world. While Bitcoin and other cryptocurrencies are built on the idea of separating financial transactions from the financial organizations of traditional currencies, Ripple is almost the opposite in every sense.  XRP by Ripple price can be found on this page alongside the market capitalization and additional stats.

XRP is trending amid highly polarized community sentiment, with many debating whether recent price drops are a "Christmas dump" or a strategic institutional accumulation phase.

AABG Token

AABBG Crypto is trending due to upcoming catalysts, including a January 2026 corporate update detailing mining and digital currency projects, alongside the highly anticipated launch of its silver-backed AABBS token and next-generation wallet.

Investors remain vigilant, emphasizing perceived market manipulation and the company's ongoing legal action to protect shareholder value.

Bed Bath & Beyond, Inc. engages in the provision of an e-commerce platform. It offers furniture and home furnishing products and services. The company was founded on May 5, 1997 and is headquartered in Murray, UT.

NVNO's Shares Decline on Unfavorable FDA Review Outcome for VenoValve

enVVeno Medical shares plunge after the FDA rejects its VenoValve PMA, citing insufficient trial data and safety concerns tied to the surgical procedure.

Medical device company enVVeno Medical Corporation (NVNO) on Wednesday announced that the U.S. Food &amp; Drug Administration (FDA) has refused to approve its application for its lead product, VenoValve, a surgical replacement venous valve for treating severe deep chronic venous insufficiency (CVI).Following the announcement, NVNO shares plunged 71% by Wednesday afternoon, at the time of writing.Severe deep chronic venous insufficiency (CVI) is a long-term condition where the veins in the legs have difficulty returning blood to the heart, leading to blood pooling and various symptoms like swelling, aching, and skin changes. This occurs primarily due to damaged or weakened valves within the deep leg veins.On Stocktwits, retail sentiment around <a href="https://stocktwits.com/symbol/NVNO">NVNO</a> rose from ‘neutral’ to ‘extremely bullish’ territory over the past 24 hours, while retail chatter rose from ‘low’ to ‘extremely high’ levels.<figure class="image"><img style="aspect-ratio:563/61;" src="https://news.stocktwits-cdn.com/Screenshot_2025_08_20_at_12_41_02_PM_png_bca2208bb7.webp" alt="NVNO's Sentiment Meter and Message Volume as of 12:40 p.m. ET on Aug. 20, 2025 | Source: Stocktwits" width="563" height="61"><figcaption>NVNO's Sentiment Meter and Message Volume as of 12:40 p.m. ET on Aug. 20, 2025 | Source: Stocktwits</figcaption></figure>A Stocktwits user expressed optimism for the company renegotiating with the FDA.<stembedurl>https://stocktwits.com/Flying_Trader2/message/625960642</stembedurl>Another user said that they see no value in the company with the VenoValve rejection.<stembedurl>https://stocktwits.com/kmx_swing/message/625941525</stembedurl>The FDA <a target="_blank" rel="noopener noreferrer nofollow" href="https://envveno.com/envveno-receives-not-approvable-letter-from-the-fda-for-the-venovalve/">said</a> in a letter that it completed its review of the company’s application for VenoValve but has decided that it is unable to approve it in its current form. The agency said that data generated by the company for the application was not sufficient on its own to determine the favorability of the benefit-risk profile for VenoValve.The FDA also raised concerns about bias and the possibility that clinical improvement occurred as a result of the patients being enrolled in a study. The agency further raised safety concerns, which were attributed to the VenoValve open surgical procedure, and which required re-hospitalizations.CEO Robert Berman said that the company is disappointed by the FDA’s decision and highlighted that a high percentage of patients in a study showed significant clinical improvement after receiving VenoValve. Berman added that the company will continue to work with the FDA on new criteria to demonstrate the safety and effectiveness of the device.The firm’s next steps may include a meeting with the FDA to discuss requirements for a potential resubmission of the VenoValve or appeal of the decision, along with appropriate next steps.NVNO stock is down by 59% this year and by about 77% over the past 12 months.&nbsp;Read also: <a href="https://stocktwits.com/news-articles/markets/equity/elon-musk-says-tesla-model-yl-might-not-ever-come-to-us-markets/chsitLlRdhq">Elon Musk Said Tesla’s Model Y L Might Not Ever Come To US Markets – Here’s Why</a>For updates and corrections, email newsroom[at]stocktwits[dot]com.
