A VIP asked me, in the crypto world, if to succeed in trading contracts, should I focus on just a few coins or cast a wide net?

First, the conclusion: To survive long-term and make stable profits, it must be "few but refined," absolutely no spreading too thin.
Experienced traders generally: 1 core main coin + 2 to 4 familiar auxiliary coins = a total of 3 to 5 is enough.
Below, I will explain the reasoning, stages, and methods all at once.
1. Why "casting a wide net" will definitely lose money (95% of people fall into traps)

1. Lack of energy
Each coin has its own temperament: volatility rhythm, capital pattern habits, linkage strength, pin insertion frequency.
Monitoring 8-10 coins at once = can't understand each, signals are blurry, stop-losses are randomly set → guaranteed liquidation.
2. Risk control goes out of control directly
Multiple coins = multiple positions = leverage is effectively amplified.
Crypto is highly interconnected; when BTC crashes, many coins crash simultaneously → chain liquidation.
3. Trading distortion, mental breakdown
Can't keep up: opening random orders, chasing rallies, panic selling, frequent stop-losses, emotional adding.
You're not trading; you're gambling.

In one sentence: beginners die from heavy positions, veterans die from too many coins.

2. Why "focusing on 1-5 coins" makes success easier

1. Master one coin = doubled win rate
Long-term only trading BTC/ETH, you'll become familiar with:
- Key support and resistance, major manipulation zones
- Funding rate patterns, major capital activity times
- Linkage strength, news sensitivity
Become so familiar that a glance at the candlestick chart tells you "whether to trade this wave."
2. Simple risk control, easy execution
3 coins, each with 5% position, total 15%, manageable leverage, easy stop-loss setting, clear review.
3. Forming a stable trading system
Only trade in familiar patterns and coins → high win rate + high risk-reward ratio, long-term compound growth.

3. How to determine the number of coins at different stages

1) Beginner (0-6 months): only 1 — BTC

- Reason: best liquidity, fewest manipulations, standard candlestick patterns, most transparent news
- Goal: practice stop-loss, position sizing, rhythm, mindset
- Strictly forbidden: ETH, altcoins, small coins, new coins

2) Intermediate (6-18 months): up to 3 — BTC + ETH + 1 mainstream (BNB/SOL)

- BTC: set direction, determine overall trend
- ETH: high volatility, many opportunities, strong linkage
- 1 mainstream: to catch specific market moves (like public chain, platform tokens)

3) Mature (18 months+): up to 5 — 3 core + 2 observation

- Core 3: monitor daily, trade daily, familiar with signals
- Observation 2: only participate lightly during major trends and clear opportunities
- Principle: don’t trade what you’re not familiar with, don’t trade unclear signals, keep position under 5% per coin

4) Never do:

- More than 5 coins at the same time
- A bunch of small-cap, low-liquidity altcoins
- Daily switching coins, chasing hot topics

4. The most stable allocation (copy directly)

- Main position: BTC (60% of effort)
- Auxiliary position: ETH (30% of effort)
- Flexible: BNB/SOL, choose one (10% of effort)
- Total coins: 3, enough to cover most market conditions.

5. One sentence summary

Less but refined is the key; casting a wide net is suicide.
Success in contracts doesn’t rely on "more," but on "familiarity," "discipline," and "risk control."
