In physical delivery, the number of positions held × the amount of delivery worth the single contract, and the seller must ensure full BTC; cash delivery is calculated based on (delivery price-opening price) × contract face value × contract number, and the reverse calculation is made when shorting. 2. The delivery price is usually the weighted average of the spot prices of multiple exchanges. 3. In terms of margin, check the maintenance margin before delivery, deduct the outstanding handling fees and return the remaining margin; perpetual contracts also need to settle the capital expenses, that is, the holding value × capital rate, etc.

The core difference between Bitcoin and Bitcoin contracts lies in their essential attributes, transaction purpose and risk characteristics. 1. In essence, Bitcoin is a decentralized digital asset with actual value; Bitcoin contracts are financial derivatives, and are based on the price of Bitcoin. 2. In terms of transaction purpose and method, Bitcoin is used for investment or payment and needs to be actually held; contracts are used for hedging or leverage speculation, and there is no need to hold physical objects. 3. In terms of risk and return, Bitcoin price fluctuates greatly but has limited risks. Contracts may lose their positions due to leverage amplification of risks and returns. 4. In terms of investor adaptability, Bitcoin is suitable for long-term investors and contracts are suitable for professional speculators.

Jul 15, 2025 pm 08:09 PM
In the future, stock tokens will promote market expansion, improve financial efficiency and liquidity through compliance, and accelerate ecological maturity through institutional entry, but they will also face challenges and risks. 1. Compliance is its core advantage, and the gradual improvement of the global regulatory framework will help it become a mainstream financing tool; 2. Blockchain technology achieves 24/7 transactions and rapid settlement, significantly reducing transaction costs and improving asset liquidity; 3. Institutional investors plan tokenized products and improve infrastructure to promote ecological maturity; 4. Cross-border compliance differences, smart contract vulnerabilities and competition on traditional exchanges are still the main challenges.
Jul 15, 2025 pm 08:06 PM
The privacy dilemma of stock tokens can be solved through technical upgrades and supervision. The main problems include address association risks, transaction strategy leakage and compliance conflicts. The corresponding solutions are: 1. Use zero-knowledge proofs (such as zk-SNARKs) to verify transactions without disclosing details; 2. Use mixers to confuse transaction paths with the privacy pool and design an AML whitelist; 3. Build a second-layer privacy network to allow selective disclosure of data; 4. Develop compliance privacy token standards to embed programmable modules. At the same time, regulatory coordination is needed through selective disclosure and off-chain verification tools, and gradient privacy protection solutions will be implemented based on scenarios in the future.

The upgrade of the stock token economic model requires sustainable development through inflation control and deflation mechanisms. 1. The dynamic issuance mechanism adjusts the issuance rate based on the network usage rate, reducing inflation when the pledge rate is high; use binding ensures that new tokens are used to incentivize specific behaviors; layered release extends the lock-in period to reduce selling pressure. 2. The destruction model reduces circulation through handling fees or repurchase; utility consumption forms deflation driven by actual demand; pledge precipitation attracts long-term holding and enhances security. 3. The dual token system separates governance and practical tokens; counter-cyclical adjustments are destroyed or repurchased when the market is down; DAO governance dynamically adjusts parameters through community voting to adapt to changes.

The plunge in OM tokens is mainly caused by the overall market downturn, deterioration of project fundamentals, regulatory or security incidents, market manipulation or insufficient liquidity, and competition and substitution effects. 1. The cryptocurrency market is generally sluggish, and the pullback of mainstream currencies has led to altcoins falling; 2. Project fundamental issues include unstable team or funds, slow product progress and selling pressure caused by token unlocking; 3. Policy risks and hacker attacks and other security incidents impact market confidence; 4. Small market value is easy to be manipulated and insufficient liquidity increases fluctuations; 5. Similar competitors perform better, causing capital outflows. Investors need to comprehensively evaluate the risks of multiple parties and pay attention to long-term value support.
Jul 15, 2025 pm 07:57 PM
The plunge in OM tokens is mainly due to the questioning of project fundamentals, excessive leverage and market makers’ withdrawal, systemic risks in the industry and a crisis of community trust. First, the Mantra Network ecosystem is progressing slowly and the authenticity of the partners is doubtful, which has led to a collapse of investor confidence; second, the increase in OM was driven by a few giant whales, and the market pullback triggered a series of liquidity and a sharp drop in liquidity; second, the US SEC's lawsuit against the RWA project and the Federal Reserve's postponement of interest rate cuts have exacerbated the selling pressure; finally, the project party's abnormal transfer of tokens to the exchange triggered "rug pull" speculation. Although it was explained as "ecological fund allocation", the lack of transparency accelerated retail sell-offs.
Jul 15, 2025 pm 07:54 PM
The flash crash of OM tokens is the result of the combined effect of leverage liquidation and market manipulation. 1. Highly leveraged long positions trigger forced liquidation when the market pulls back, forming a negative feedback loop of "fall-clearing-resuming" and the automatic liquidation mechanism of the decentralized lending platform aggravates price slippage when liquidity is insufficient; 2. OM tokens are concentrated in liquidity, and there is the possibility that large investors can create panic and make profits through the "smash-low-buy" strategy. Abnormal transfer data on the chain may support manipulation behavior; 3. If the project party lacks liquidity management and market protection measures, it will further amplify the market vulnerability; 4. This incident warns investors to be vigilant about the risks of high leverage and low liquidity assets. At the same time, it calls on regulators and project parties to strengthen market monitoring, optimize risk control mechanisms and liquidity design to maintain market stability.
Jul 15, 2025 pm 07:51 PM
OKX and Binance urgently upgraded risk control measures against the OM token plunge. 1. The OM token crash exceeded 50% on May 28, which was suspected to be due to large-scale sell-offs or insufficient liquidity, which caused users to question the risk control system; 2. OKX introduced a "large-value order circuit breaking mechanism" and strengthened the monitoring of suspicious accounts, while Binance enabled a risk margin system and real-time liquidity monitoring tool to optimize the transaction monitoring system; 3. Industry reflection pointed out that small and medium-sized tokens are easy to be manipulated, and transactions require strengthening the project review mechanism to build a more stable digital asset ecosystem.
