In the cryptocurrency world, a field full of opportunities and risks, how to conduct effective project investment research is an important issue that every investor must face. Below we will introduce some practical project investment research ideas in detail.
1. Clarify investment research goals and your own positioning
Before beginning investment research, you must first determine your investment goals. Are you pursuing short-term high returns or focusing on long-term asset appreciation? Different goals determine different investment research directions and strategies. At the same time, you must have a clear understanding of your risk tolerance and assess how much investment loss you can withstand to select projects that are suitable for you. For example, investors with a lower risk tolerance may prefer to choose mainstream cryptocurrency projects with larger market capitalizations and greater stability; while investors with a higher risk appetite may focus on emerging projects with greater potential but also relatively higher risks.

Rolling positions is a commonly used swing trading strategy in stock, futures, and other markets. The core logic is to reduce holding costs by building positions in batches and rolling trades while capturing short-term profits from market fluctuations. The operation line is clear and needs to be strictly executed in conjunction with market trends, stock characteristics, and fund management. The following are specific operational methods:
1. The core logic and applicable scenarios of rolling positions
The essence of rolling positions is a combination strategy of 'base positions + swing trading': by holding a certain proportion of base positions for a long time to lock in core profits while using remaining funds to buy low and sell high amid stock price fluctuations, constantly reducing overall holding costs.

Solana is a high-performance blockchain platform known for its extremely fast transaction speeds and low fees. It combines Proof of History (PoH) and Proof of Stake (PoS) mechanisms to handle thousands of transactions per second. In 2025, the Solana ecosystem continues to thrive, attracting a large number of projects in DeFi, NFTs, and blockchain gaming. Its price performance is also impressive, steadily climbing and continuously breaking new highs under the overall positive market trend. For instance, on some DeFi lending platforms, the loan volume based on Solana has significantly increased, allowing users to engage in lending operations at a lower cost, thanks to Solana's efficient performance.

In the enchanting realm of cryptocurrency, stories of wealth easily capture public attention. Internet celebrity Liangxi boldly shorted during the epic crash of the cryptocurrency market on '5.19' in 2021, turning an initial capital of 1,000 yuan into 30 million through rolling positions, achieving an instant turnaround of wealth and becoming famous overnight. However, such success is not a common phenomenon. More often, rolling positions carry enormous risks, akin to dancing on the edge of a cliff; a slight misstep can lead to a fall into an abyss.

So, what exactly is rolling positions? In simple terms, rolling positions are a strategy of gradually increasing positions in a one-sided trend market, using multiple amplifications of the position to accumulate profits through the compounding effect. Its core lies in 'low-risk trial and error → profitable position addition → stop-loss protection → expanding profits when the trend continues.' It differs from ordinary position addition by emphasizing operations based on unrealized profits, achieving exponential growth in returns through gradual position expansion. This strategy utilizes the power of market trends while dynamically adjusting positions to reduce risks, achieving a delicate balance between risk and reward. However, this balance is extremely fragile; even a slight misstep can lead to severe consequences.

In the magical realm of the cryptocurrency market, countless individuals flock here with dreams of overnight wealth. Among them, the trading strategy of 'rolling positions' is like a mysterious magic spell that attracts many investors' attention. It can be the key to unlocking the door to wealth or an accelerator leading to a deep abyss. Today, let us delve into the mysteries of rolling positions in the cryptocurrency market.
1. What Exactly is Rolling Positions?
In simple terms, rolling positions is a method of increasing positions based on existing profitable positions to expand returns. In the cryptocurrency market's unidirectional trend, the rolling position strategy is frequently used, aiming to amplify positions multiple times to achieve rapid accumulation of returns through the compounding effect. The core process is: low-risk trial and error → profit increase → stop-loss protection → expand returns when the trend continues. For example, if you buy 1 Bitcoin for $10,000 and the price rises to $11,000, you make a profit of $1,000. At this point, you use this $1,000 profit to increase your Bitcoin holdings by a certain percentage, which is the basic operation of rolling positions.

In the wave of the digital economy, the cryptocurrency space attracts the attention of many investors with its unique charm and high return potential. However, its high risks and complexities deter many newcomers. Don’t worry, this article will comprehensively unlock the basic operations of the cryptocurrency space, share practical experiences, and help you take the first step towards stable investment.
1. Understanding Key Roles in the Cryptocurrency Space
(1) Cryptocurrency: The New Nobility of the Digital World
Cryptocurrencies are decentralized digital currencies based on blockchain technology. Bitcoin, as the pioneer, with its scarcity of 21 million coins and decentralized nature, has become the preferred choice for safe-haven assets and value storage, as shown in Image 1. Ethereum expands the application boundaries of blockchain, with its smart contract functionality giving rise to numerous innovative projects. In addition to mainstream coins, there are also various distinctive cryptocurrencies like Litecoin and Ripple, each playing roles in different scenarios and enriching the cryptocurrency ecosystem.

Many partners have just entered the circle and don't know the difference and basic concepts between isolated margin and cross margin. Today, I will talk about what isolated margin and cross margin are!
1. Isolated Margin Mode
The margin required when opening a position will be used as the fixed margin for the contract's position.
When using the isolated margin mode, two-way positions can be held. The risk of short positions and long positions are calculated independently. The two-way positions of each contract will independently calculate their margin and profit.
Advantages of isolated margin mode: Liquidation will only lose the position margin, that is, the amount of the position margin is the maximum loss. Only the margin amount of the position in that direction will be lost, and other funds in the contract account will not be affected.

In the world of financial derivatives trading, position management is the core element that determines the success or failure of trades. The full margin and isolated margin modes, as two mainstream margin models, profoundly impact investors' risk tolerance and potential returns. For traders new to the market, the distinction between these two modes is like a compass for a ship, determining the direction of capital navigation in turbulent waves. This article will comprehensively analyze the core differences between full margin and isolated margin from dimensions such as essential definitions, risk mechanisms, and applicable scenarios, providing clear decision-making references for traders.

1. Basic Concepts of the Cryptocurrency Market
(1) The Essence of Cryptocurrencies
Cryptocurrencies are a new asset form based on blockchain technology, fundamentally different from traditional currencies. Unlike fiat currency, which is issued and controlled by governments or central banks, cryptocurrencies rely on decentralized blockchain networks to operate, with numerous nodes in the network jointly maintaining transaction ledgers to ensure data accuracy and immutability. For example, Bitcoin’s issuance mechanism is algorithm-based, with a fixed total of 21 million coins, not controlled by any single entity. This decentralized characteristic fundamentally changes the issuance and circulation model of currency.

In the cryptocurrency market, which operates 24/7 and has volatility far exceeding traditional financial markets, K-line charts serve as 'holographic recorders' of price fluctuations, making them an essential analytical tool for every trader. Compared to traditional markets like stocks, the high leverage characteristics and frequent extreme conditions in the crypto space further highlight the core value of K-line analysis in risk control and opportunity capture. This article will systematically dissect the composition logic, classic patterns, and practical techniques of K-lines, helping traders establish a scientific technical analysis framework.

I. Overview of the Ethereum Market
In the vast landscape of digital currencies, Ethereum (ETH) occupies a crucial position, second only to Bitcoin. Its uniqueness lies not only in being a well-known cryptocurrency but also in building a powerful smart contract platform that provides a running ground for countless decentralized applications (DApps). This characteristic greatly expands the application scenarios of Ethereum, from decentralized lending and trading in the financial sector to decentralized identity verification and supply chain management in non-financial areas, where we can see Ethereum's presence.

In the grand landscape of the global financial market, the cryptocurrency sector resembles a mysterious sea full of variables and opportunities, constantly attracting the attention of numerous investors and practitioners. Currently, the cryptocurrency sector is undergoing a series of profound changes, with many news events intertwining and colliding, outlining its unique development trajectory and laying the groundwork for future directions.

Bullish's application for listing stirs waves
July 20, 2025, is a day worth remembering for the cryptocurrency world. Bullish, which boasts the renowned cryptocurrency exchange Bullish and the leading media Coindesk, officially submitted registration documents to the U.S. SEC, knocking on the door to being listed on the New York Stock Exchange. This news instantly ignited market enthusiasm and became a focal point of discussion. Established in 2021, Bullish is incubated by powerful forces including the blockchain company Block.one and Silicon Valley star investor Peter Thiel. Its business segments are clear; since its establishment until the end of the first quarter of this year, Bullish's total trading volume has exceeded $12.5 trillion, with the global spot trading volumes for Bitcoin and Ethereum in 2024 reaching approximately $284.8 billion and $144.5 billion, respectively. In the first quarter of 2025, the average daily trading volume exceeded $2.5 billion, ranking among the top five in related spot trading volumes, competing alongside industry giants like Binance, Coinbase, and Kraken. Meanwhile, Coindesk, under its umbrella, is a key data, index, activity provider, and leading media outlet in the cryptocurrency sphere, serving 171,000 professional users globally as of the end of this first quarter, with its media site attracting 55 million unique visitors in 2024. Bullish's application for listing is expected not only to further expand its business landscape with the help of the capital market and enhance its brand influence but also to inject a strong dose of confidence into the entire cryptocurrency sector, boosting market confidence in the cryptocurrency field.

In the world of cryptocurrencies, the noise and frenzy seem never to cease, but Bitcoin is currently experiencing an unusual state—not a frenzy rushing toward historical peaks, but a deep silence before the storm. This silence is not the market's demise but a necessary phase of energy accumulation, hiding signals that could reshape the industry's landscape.
From the price trajectory perspective, Bitcoin has been consolidating in a key range for many days, with volatility dropping to a near-year-low. The once-volatile market, where daily fluctuations exceeded 10%, is now replaced by slight tremors measured in a few decimal places. Trading volumes on exchanges continue to shrink, discussions on social media have noticeably cooled, and even once-active quantitative trading bots are caught in a 'strategy failure' dilemma. Beneath this surface calm lies an intense battle between bulls and bears across multiple dimensions, including the macroeconomic cycle, regulatory policy directions, and breakthroughs in technological innovation.

In the brilliant starry sky of the cryptocurrency space, Bitcoin and Ethereum are undoubtedly the two brightest stars. With their unique charm and strong influence, they attract the attention of global investors, becoming the focal point of the digital currency field.

In cryptocurrency trading, rolling over is a complex strategy with certain risks. Rolling over usually refers to investors further increasing or adjusting their positions based on market changes, aiming for greater profits. Given the high volatility and risk characteristics of the cryptocurrency market, rolling over can bring substantial profits but also lead to significant losses. A deep analysis of rolling over in the cryptocurrency space helps investors understand and utilize this strategy better and manage risks effectively.

1. In-depth research and selection of potential coins
Long-term investment in mainstream coins: Mainstream cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH) have high market recognition and relative stability. Although their prices are highly volatile, they show a growth trend in the long term. For example, during past market cycles, Bitcoin has repeatedly broken historical highs. Investors can invest a certain percentage of funds (e.g., 100 - 500U) monthly in mainstream coins through regular investment. When the price shows a 10% - 15% pullback, increase the position appropriately to average the cost and hold for long-term appreciation.

If your account funds are below 1 million, and you want to make short-term profits in the crypto market, there is a tried-and-true 'MACD trading method' that is simple and practical, allowing retail investors to easily get started.

In the complex landscape of the financial market, going long on contracts is a common and attractive trading strategy. It provides investors with opportunities to profit in an upward market trend; however, to truly master this strategy and achieve profit goals, one needs a deep understanding and comprehensive grasp of it.
Basic concepts of going long on contracts
In simple terms, going long on contracts means that investors expect the price of a certain asset (such as digital currency, futures, stocks, etc.) to rise in the future, so they buy the asset through signing a contract and wait to sell the contract after the price rises to profit from the difference. This trading method does not involve directly holding the physical asset, but is based on the judgment of the asset's price trend for contract trading.
