Trading

Buying stocks with USDT means using a digital asset account and stablecoins such as USDT as the funding source for stock market trading. After completing account registration, identity verification, and stock account activation, users can transfer USDT into their stock account, search for target stocks on the Gate Stocks platform, and submit buy or sell orders. This process bridges the digital asset market with traditional stock markets, enabling unified management of global assets under a single account.

Real World Assets (RWA) are progressively transitioning from tokenization to on-chain financial applications, with derivatives markets widely considered the next critical frontier. Using Variational as a case study, this article examines how traditional financial liquidity flows into DeFi, how the ecosystem architecture is evolving, and the pivotal role RWA derivatives could play in the future.

RFQ (Request for Quote) has increasingly become a key trading mechanism in the on-chain derivatives market. Unlike conventional order book trading, RFQ enables traders to secure more competitive execution prices by soliciting real-time quotes from liquidity providers, while also mitigating issues such as slippage and liquidity shortages.

The key distinction between USDG and USDC/USDT lies in their stablecoin economics: with USDC and USDT, the reserve yield is mainly retained by the issuers Circle and Tether, meaning platforms that drive adoption rarely have a systematic way to share in those returns. In contrast, USDG operates within Paxos’ compliant issuance framework and, through the GDN, allocates up to approximately 97%–100% of its reserve yield to approved network partners, rather than letting a single issuer capture all the value.

PSK (319660) is the KOSDAQ-listed stock code for PSK Inc., a South Korean manufacturer specializing in semiconductor front-end process equipment and 3D packaging equipment. Spun off from PSK Holdings and listed independently in April 2019, the company is headquartered in Hwaseong, Gyeonggi Province. Its operations span core wafer fabrication processes including Dry Strip and Dry Cleaning, along with the SEMIgear advanced packaging product line.

The key distinction between PSK and most of its Korean semiconductor equipment peers stems from process node scope and product boundaries: PSK specializes in front-end dry strip, dry cleaning, and bevel etch—specific photoresist removal and cleaning segments—while extending into 3D packaging through SEMIgear. In contrast, other domestic Korean equipment makers also encompass plasma etching, deposition, back-end heat treatment, probe testing, and packaging assembly, resulting in distinct competitive landscapes for each company based on their position in the fabrication process.

The key difference between PSK Inc. and PSK Holdings lies in their respective listed entities and business roles: the former (KOSDAQ 319660) handles semiconductor front-end process equipment, while the latter (KRX 031980) remains the surviving entity, retains the holding company function, and focuses on back-end and advanced packaging equipment. On April 1, 2019, the original PSK Group underwent a management and business split, and the two entities have since operated and reported independently. Although both are headquartered in Hwaseong, South Korea, and belong to the semiconductor equipment sector, they should not be regarded as the same publicly traded entity.

PSK Inc. (319660) spun off from PSK Holdings in 2019 and went public independently on KOSDAQ. The company specializes in front-end semiconductor equipment, including Dry Strip and Dry Cleaning tools, alongside SEMIgear 3D packaging solutions; on Gate Stocks, the Korea Stock Zones allow users to perform Traders on KRX-listed stocks with settlement in USDT. The ticker 319660 is identical to that on the domestic KOSDAQ market. Regular trading runs from 09:00 to 15:20 KST, with prices shown in KRW and Traders settled in USDT.

WhiteBIT Coin (WBT) is the native utility token issued by the WhiteBIT exchange, with a fixed total supply of 400,000,000 tokens that cannot be increased. It also serves as the native Gas coin on the Whitechain blockchain. WBT is deployed across three networks: Whitechain, Ethereum (ERC-20), and Tron (TRC-20). Users gain platform benefits — including trading fee discounts, free withdrawals, and Launchpad access — through two mechanisms: Owning (held in the main account) and Holding (locked token holdings).

Whitechain is WhiteBIT's PoA, EVM-compatible L1, with WBT serving as the native Gas token. For cross-chain transfers, WBT must first be burned on Ethereum or Tron, and an equivalent amount is minted on Whitechain by providing the burn transaction hash. The SoulDrop smart contract allocates the user participation fund and on-chain transaction fees to WB Soul users who both hold WBT Holding and have completed KYC. Rewards are calculated over a 30-day period and compounded based on the user's Holding tier.

On WhiteBIT, completing WBT Holding and earning its benefits is a repeatable process. Users register, deposit, and purchase WBT, then transfer tokens from their main account to the locked Holding account. Based on the amount of tokens held, they activate tier-specific platform benefits. Holding benefits include trading fee discounts, free withdrawals, and Launchpad access. WBT transferred to Holding also counts toward Owning, and both benefit types are stackable.

SOXL is a leveraged ETF that tracks three times the daily return of the U.S. semiconductor sector index, designed primarily for investors seeking to amplify short-term upside in the semiconductor market. It achieves leverage through financial derivatives, rather than holding three times the underlying stock assets directly.

MiCA (Markets in Crypto-Assets Regulation) establishes a unified EU regulatory framework for cryptocurrencies, outlining clear requirements for token issuance, exchange listings, stablecoin management, and information disclosure. MiCA will not prohibit the trading of mainstream cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH); however, certain stablecoins, privacy coins, high-risk tokens, and projects lacking compliance disclosures may face stricter oversight. For cryptocurrency exchanges, MiCA mandates that listed assets possess more comprehensive information disclosure and a clearly defined legal liability entity.

Yangtze Optical Fibre and Cable Joint Stock Limited Company (HKEX: 6869) is a global leader in manufacturing optical fiber preforms, optical fibers, and optical cables, and is one of the representative communication infrastructure companies on the Hong Kong stock market.

Currently, leading international digital asset firms including Gate, Crypto.com, OKX, Bitstamp, MoonPay, Bitpanda, and Coinbase have either obtained or are pursuing MiCA authorization. With a MiCA license, exchanges can operate across multiple EU member states through the Passporting mechanism without needing to reapply for local permits. The MiCA license is rapidly becoming an essential gateway for cryptocurrency exchanges to enter the European market and a key benchmark for assessing a platform's regulatory compliance.
