Continuing to organize what newcomers in the crypto space should understand first.

On October 21, 2026, Bitcoin fluctuated around $84,000, down about 33% from last year's historical high of approximately $126,000 in October, while Ethereum was around $2,480, with a deeper drop. In the past month, the price has basically bounced between $80,000 and $87,000. The volatility doesn't seem extreme, but behind this is the fact that the Federal Reserve has raised interest rates to 3.75%-4.00% in September, inflation data is hot, and further rate hikes are possible in October and December. Oil prices have surged above $100 due to the situation in the Middle East. In this environment, the most common mistake newcomers make is not misunderstanding metrics, but rather going all in and leveraging, thinking that finding a “must-rise signal” will lead to a turnaround. What truly allows an account to survive the next round of uncertainty has never been technique, but position management.

Below are several directly usable principles for position management:

1】First determine "how much loss is acceptable," then decide how much to buy

The starting point of position management is not “I am optimistic about this coin,” but rather “to what extent can I lose this money and still continue to live and operate normally.” Historical retracements in the crypto space are harsher than most people imagine. Bitcoin dropped about 77% from its peak in 2021 to its low in 2022, over 80% from 2017 to 2018, and a similar magnitude from 2013 to 2015. The drop from last October's high to this June's low also exceeded 50% at one point. The math is simple: a 50% drop requires a 100% rise to break even, and a 75% drop needs a 300% rise. If you have $100,000 in principal, fully leveraged in a single coin, when it drops to $25,000, many people can no longer sleep, use leverage to break even, or simply liquidate their position and exit.

The specific approach is to first set a maximum allowable loss for a single transaction. Newcomers are advised to limit a single trade or a single asset to a maximum allowable loss of no more than 1%-2% of the total account. Assuming an account of $100,000, the single trade risk should be controlled at $1,000-$2,000. If Bitcoin is currently at $84,000 and you plan to set a 15% stop loss (down to about $71,400), then the position size is risk amount divided by stop loss percentage. For example, if the risk is $2,000 and the stop loss is 15%, the position size is about $13,333, or about 13% of the total account. The remaining money should either be put into stablecoins or diversified into other unrelated assets.

Case comparison: Assume someone went all-in with $50,000 in Bitcoin near last year's peak, and by June this year, the account shrunk to below $25,000; psychological pressure would have caused most people to exit near the bottom. If at that time the position had only been 30%, leaving 70% in cash or stablecoins, the same percentage drop would have only shrunk the account by about 15%, still having the ability to buy in batches at low prices. Currently fluctuating around $84,000, no one knows if it will test $80,000 again or surge directly to $90,000, so fixing the position first is more important than guessing the direction.

2】Fixed proportion positions are more resilient to volatility than fixed amounts, but cash must be reserved

Many people like to think, “I buy $10,000 worth of Bitcoin each time.” This seems fine in a rising market, but once in a deep correction, the account will become heavier. A better approach is fixed proportion: maintaining a core position as a certain percentage of the total account long-term, while keeping the rest as operational capital.

Currently, it is recommended that newcomers keep their core position at 20%-40% of the total funds (mainly Bitcoin and Ethereum), with the remaining capital in stablecoins or short-term government bonds. Why? Because the current macro environment is clearly tight. The Federal Reserve has just finished raising rates, and the yield on 10-year U.S. Treasuries is around 5%, while oil prices are high due to geopolitical conflicts. The correlation between crypto assets and risk assets remains high. If another rate hike occurs or the Middle East situation escalates, it would not be surprising if the $80,000 mark is breached. The importance of holding enough cash is not to miss the uptrend, but to ensure that when prices drop to your predetermined buyback range, you actually have the funds to buy, rather than just watching.

Data comparison: In the bear market of 2022, Bitcoin dropped about 77% from peak to low. If fully invested, the account would have nearly gone to zero, leading to psychological collapse. If starting with a 40% position and 60% in cash, by the time it fell to the low, the overall account would have only retraced about 30%. Later, using cash to buy back the position to 60%, when it recovers in 2024-2025, the overall return would far exceed those who went all in to the end and exited midway. Now, having retraced 33% from the peak, the recent volatility is not extreme, but don’t reduce your cash ratio to below 10% just because “it hasn’t dropped recently.”

3】Leverage and perpetual contract positions must be cut by half

Spot positions and perpetual positions are two different things. Perpetual contracts have funding rates, liquidation prices, and liquidity in opposite trades. Currently, the funding rate for Ethereum is mostly positive across exchanges, with an 8-hour rate around 0.001%-0.01%; while not particularly high annually, it can reverse quickly with sudden market declines, triggering liquidation chains. Recently, Bitcoin fluctuated between $80,000 and $85,000, with liquidation prices for leveraged traders often concentrated below $80,000 and above $87,000.

If newcomers want to try perpetuals, it is recommended that the risk for a single trade is further reduced to 0.5%-1% of the total account, and stop losses and liquidation alerts must be properly set. A more prudent approach is to only use spot trading or apply very low leverage (below 2x) while keeping ample margin. Historical data shows that most retail liquidations occur within a few hours of rapid price movement, not during slow declines. During the descent from the high in 2026, there have already been several instances of daily or weekly fluctuations exceeding 10%.

Example: Assume someone used 5x leverage to long Bitcoin around $86,000 with an account of $100,000; after opening a position, the margin requirement was about $20,000. If the price drops to $82,000 (about a 4.7% drop), the unrealized loss is approaching 23% of the account, close to many exchanges' margin call thresholds. Further declines make liquidation very likely. For the same price fluctuations, if only using spot and the position is controlled at 30%, the unrealized loss would only be about 1.4%, making it completely feasible to hold or average down as planned.

4】In the face of the uncertainties of rate hikes and war, first calculate the "worst-case scenario"

Currently, the market pricing indicates a possibility of further rate hikes at the end of October's Federal Reserve meeting, with a higher likelihood in December. If oil prices surge again due to the Middle East situation, inflation expectations will follow, putting pressure on risk assets. After Bitcoin's 33% retreat from the high, it is not already in a state of “no more room to drop”; historically, drops of over 50% are not uncommon.

The specific approach is to conduct a stress test. Calculate the net value of the account assuming the current position drops by 30% and 50%. Assuming total funds of $100,000, with a core position of 30% ($30,000 in Bitcoin), if it drops by 30% to around $59,000, this portion becomes $21,000, making the total account $91,000, a 9% retracement. If it drops by 50% to around $42,000, the position becomes $15,000, and the total account $85,000, a 15% retracement. Such amplitudes are bearable for most people and won’t trigger emotional trading. If it turns out that a further 30% drop would shrink the account by over 40%, it indicates the position is too large and must be reduced.

Simultaneously, set multiple exit lines: if the price breaches a key support level (like $80,000 or a previous low), first reduce the position by 20%-30%; if the total account retraces 15%, enforce margin reduction or position reduction; when macro events (rate hikes or escalation in geopolitical conflicts) occur, stop adding new positions and observe for a week before deciding whether to add. Do not bet all your judgment on "this time is different."

5】Building positions in batches and rebalancing is more stable than a one-time bet

The current price is around $84,000, still distant from its peak but not cheap either. Newcomers should not try to catch the bottom with a single large entry. Use time-based batching: for example, buying a fixed amount weekly or bi-weekly, gradually converting cash into a core position. Alternatively, use price-based batching: if it drops below $82,000, add a portion, and if it falls below $80,000, add another portion, with each addition not exceeding 20% of the remaining cash.

Rebalancing is equally important. If Bitcoin rises to $95,000 and the position increases from 30% to 45%, then reduce part back to 30%-35%; if it drops to $75,000, and the position falls to 22%, use cash to buy back. This action may seem simple, but it forces you to sell at highs and buy at lows, rather than the opposite.

Data shows that in the past several cycles, accounts that strictly follow fixed proportion rebalancing typically recover faster after deep retracements compared to timing accounts, as timing traders often find themselves out of funds near the bottom or fully invested in the middle of a rise.

6】Recording and reviewing is more important than finding a new indicator

Each time you open a position or adjust your holdings, record the current account net value, position ratio, stop-loss positions, and reasons for making this decision. Three months later, review which actions were driven by emotions and which were guided by rules. The crypto space offers accessible data for backtesting, but what truly separates the successful from the unsuccessful in live trading is execution discipline. Many people may backtest and find high Sharpe ratios, yet in practice suffer significant drawdowns (20%-30%) due to uncontrolled positions, leading to an inability to execute their original plans.

Remember, technical indicators, funding rates, and on-chain data can help you judge direction but do not resolve the question of "what if this judgment is wrong." Position management addresses this issue. In an environment where the interest rate cycle is not yet fully concluded and geopolitical risks may escalate at any time, ensuring your account survives the next round of uncertainty is more critical than capturing a perfect rebound. Backtesting can prove the validity of a certain set of rules historically, but what truly allows you to remain in the market is when these rules temporarily fail, your position hasn’t eliminated you from the game.

Write down the above points, calculate the numbers according to your capital size, and then decide on the next steps. Stabilizing your account has never been about finding a better indicator, but rather ensuring that any mistake in judgment does not lead to your immediate removal from the market.
