Futures Trading has two types of Margin modes, but many people do not understand and often select incorrectly, resulting in inexplicable losses.
Cross margin mode: All the money in your account can back up your unfortunate position. If one position incurs a loss, the system automatically adds Margin from other idle funds, which is equivalent to "buying the dip." Sounds good? But it's a double-edged sword - if the market reverses wildly, it could burn down your entire account.
Isolated Margin Mode: The maximum loss for a position is just the amount of money you allocated to it, while other funds remain untouched. Safe, right? But the cost is that you need to manually add Margin, and if you're not careful, you could get liquidated, placing all the risk control pressure on yourself.
Actual example: both have a principal of 2000U, using 1000U to open a 10x BTC long position.
- Isolated margin guys: BTC dropped to the liquidation price, lost 1000U and got liquidated, the account still has 1000U.
- Full Margin Bro: BTC dropped by 1000U, that's

After days of silence, Musk finally expressed his stance on the U.S. 100% tariff policy against China, but this time it was not a thumbs up - rather, it was a splash of cold water.
What is his core concern?
Tariffs seem to protect domestic industries, but in reality, they indirectly raise the R&D costs for startups. With higher import costs for chips and raw materials, the time to market for new products is extended, and the technological competitiveness of the United States is consequently hindered. In simple terms: today's tariff policies may be the seeds of tomorrow's decline in innovation.
The market reaction has already given a signal.
Investors have sensed the unstable factors. The trade war is escalating, large funds are starting to watch from the sidelines, and risk assets are under pressure. Even the crypto market is experiencing fluctuations—DOGE has risen over 12%, but this is more due to speculative expectations rather than a solid improvement in fundamentals.
Interestingly, Musk has a different attitude towards interest rates.
He supports Federal Reserve Chairman Powell's decision to pause interest rate cuts. In his view, aggressive easing policies are the real drivers of inflation.

The Bitcoin Halving mechanism aims to halve the miners' rewards after every 210,000 Blocks are mined, thereby reducing the supply of new coins.

The price movement is influenced by multiple factors including supply and demand, adoption, regulation, technological advancements, and market sentiment, which need to be considered comprehensively to formulate investment strategies.

Recently, there have been reports in the crypto world that "China is going to lift the ban on Bitcoin to build strategic reserves," and BTC surged at one point. However, after reviewing official data and legal documents, I reached three conclusions:
Current situation: The ban hasn't been lifted.
The timeline is actually very clear:
- 2021 - The State Council + ten departments jointly banned crypto trading and mining (this is a big move)
- November 2024 - A Shanghai court ruling states that personal possession of Bitcoin is "not illegal", but commercial activities are still prohibited.
- March 2025 - Rumors suggest that China is considering a reserve of 195,000 BTC, but this is all unconfirmed speculation.
Key details: The ban targets trading activities and the mining industry, not the ownership itself. This is completely different from lifting the ban.
Why is the official attitude indifferent?
Two core contradictions:
1. Control rights conflict
- The People's Bank of China is promoting the digital renminbi (CBDC), aiming for full control.

Elon Musk has achieved tremendous success in fields such as the internet, aerospace, new energy, and artificial intelligence through innovation and cross-industry investments, accumulating a fortune of $244 billion.

Italy has significantly changed its encryption tax rules at the beginning of 2023, and now there are two tax systems to choose from:
Plan A: Capital Gains Tax 26%
- Only counts when trading, selling coins/exchanging coins/spending coins all require payment.
- Only profits exceeding the threshold of 2000 euros are subject to taxation.
- The formula is simple: ( selling price - buying price ) × 26%
Option B: Alternative Value Tax 14% (Cost-saving option)
- Only need to declare the portfolio value once a year on January 1st
- The same profit part × 14%
- Equivalent to cutting 26% down to 14%, saving nearly half the tax.
For example: Buying 100 SOL for 2000 euros, then selling for 4000 euros.
- Profit = 2000€
- Option A: Pay 520 euros in tax (26%)
- Choose option B: Pay 280 euros in tax (14%)
Key points:
- Mining, staking, airdrops, and gifts are all considered taxable events.
- As long as it exceeds 2000 euros, it is required.
