From "Mystical Trading" to "Rational Calculation": Understanding These Crypto Formulas Can Double Your Assets Without Relying on Luck

Many newcomers rush into crypto with the first reaction being "look at the candlesticks" and the second being "listen to rumors." But in the brutal market of bull and bear cycles, those who truly survive and accumulate assets are often the ones who calculate clearly. The recently circulated "Understanding the Basics of Crypto Formulas (Part 2)" sums it up very well. Today, we'll break down these formulas from a practical analysis perspective to see the survival codes hidden behind the numbers.

I. Spot Trading and NFTs: Don't Let Your "Purchase Cost" Fool You

For beginners, the most common pitfall is focusing only on the purchase price while completely ignoring fees. Formulas 1, 2, 3, and 15 in the chart clearly indicate the true cost. Purchase cost price = (Total purchase amount + Fees) ÷ Quantity purchased. In frequent trading or small-amount dollar-cost averaging, high fees can eat up all your floating profits.

Even more noteworthy is Formula 5: Average holding cost. If you buy in batches (e.g., grid trading) without calculating the average cost, you won't even know if you're in profit or loss. For NFT traders, Formula 15 is particularly critical: Purchase price + Fees + Minting cost. Many people only focus on the bid price, only to find that high gas fees and platform fees make the NFT a loss from the start. Learning to calculate Return on Investment (ROI) is the prerequisite for making a good trade.

II. Derivatives Trading: The Key to Surviving "Liquidations" Lies in Calculating the Liquidation Price

Derivatives trading is both the gateway to profits and the abyss of liquidation. Formulas 6-10 in the chart accurately outline the core of derivatives. Margin = Contract value ÷ Leverage. This basic formula directly determines how much adverse price movement your capital can withstand.

The most important formula to memorize is Formula 10: Liquidation price: Entry price ± (Margin ÷ Leverage × Entry price ÷ Leverage) ÷ Direction. Many traders get liquidated by "flash crashes" because they open positions based on feeling without precisely calculating the price level that would trigger forced liquidation. Pay close attention to the direction: For long positions, you subtract; for short positions, you add. Only by knowing exactly how far you are from the liquidation line before opening a position can you set reasonable stop-losses and avoid going to zero in extreme market conditions.

III. The "Magic" of Interest Rates: Don't Mistake APR for Annualized Yield

In the DeFi staking and farming craze, many are misled by high APR. Formulas 11-14 in the chart clearly remind us: APR (simple interest) and APY (compound interest) are vastly different.

Formula 13: APY = (1 + Daily rate)^365 - 1. This exponential growth model is extremely powerful. Many protocols advertise a daily rate of only 0.1%, which seems insignificant, but the actual annualized yield (APY) can reach over 44%. To calculate real compound returns, Formula 14: Compound returns = Principal × (1 + Annual rate)^Investment years - Principal is essential. Extending the compounding period reveals that this is one of the most reliable ways to accumulate wealth in crypto, aside from "100x coins."

IV. Mining and Funding Rates: Those "Hidden" Net Asset Killers

In the "Wei Yi curve" or related mining models, the chart's "daily mining income" formula (Formula 2) is brutally realistic: Hashrate × Block reward × Coin price × (1 - Fee rate). This tells us that no matter how high the hashrate, if the coin price plummets, mining income will still be negative.

Additionally, many perpetual contract traders overlook a hidden cost—funding rates (Formulas 4, 5). In a bullish market, long positions need to pay funding rates to shorts. If settled daily, Formula 5: Annualized funding rate cost = Funding rate × Settlements per day × 365 × Position value ÷ Margin. Even if your direction is correct, holding positions overnight long-term can result in significant "overnight fees," directly dragging down your final profit-loss ratio.

Final Thoughts:

Crypto is not a casino; it is a highly digitalized financial derivatives market. Understanding these basic formulas is not about becoming a math teacher, but about avoiding risks and optimizing capital efficiency. Market sentiment can fool you, and influencers' calls can fool you, but if you have a clear mathematical logic in your mind and know exactly where your costs are, where your liquidation line is, and what your real return rate is, you will already have an edge over 70% of the market participants who trade based solely on emotion and intuition in this brutal zero-sum game. Understand the formulas, calculate clearly, and that is the foundation for surviving in a bull market.
