Crypto Guides: Learn, Practice & Grow

Welcome! These guides are written to help real investors make calmer, smarter decisions. They are intentionally long, practical, and example-heavy. Take your time. The more you read, the better you'll navigate markets that move fast and test your patience.

1 Using the Profit / Loss Calculator the Smart Way

Plan entries/exits and track positions with live pricing.

The calculator exists to remove guesswork and emotions from your decisions. Before buying, you can simulate various entries, fees, and potential exits, so the trade already has a clear plan. After buying, you can monitor your position with live pricing. When markets are volatile, the tool keeps you grounded in math rather than mood.

Enter your quantity, buy price, and any fees. If you don't fill the "Sell/Now Price" field, the calculator automatically fetches the live price. You'll see your net PnL, ROI, and breakeven. These three numbers tell a simple story: where you are, how far you've come, and what price would erase your loss if you needed to exit.

Think in ranges, not single points. For example, create a "comfort band" around breakeven: maybe you're comfortable if price is 2–3% above it and on track to your first target. If price hovers slightly below breakeven but your thesis is intact, you might size smaller rather than panic. Tools don't predict; they help you decide with clarity.

  • Pro tip: Add fees from both entry and expected exit. Small fees compound over many trades.
  • Mindset: The goal isn't to be right, it's to be prepared.

2 DCA (Dollar-Cost Averaging) Without Stress

Turn volatility into an ally via consistent buys.

DCA is a way to turn volatility into an ally. Instead of guessing the best day to buy, you decide a schedule and a fixed dollar amount. Over time, you build a position at a blended average price. This structure protects you from the classic traps: buying everything on a peak or freezing during dips.

Pick a coin you actually believe in for the long term. Set a realistic amount (for example, $50 per week) that won't pressure your monthly budget. Use our DCA tool to simulate 6–24 months and get a sense of how many coins you would accumulate and what they'd be worth at current prices.

Automation reduces emotional errors. Many exchanges let you schedule recurring buys. Consider pausing DCA only if your personal finances change or the coin's fundamentals deteriorate. Otherwise, the consistency of DCA is the edge.

  • Quality over quantity: two or three strong assets often beat a big basket of unknown tokens.
  • Stay liquid: keep a small cash buffer to avoid selling at the worst time if life throws a surprise.

3 Breakeven: The Most Underrated Number

Your emotional anchor for rational actions.

Breakeven is not just a math output. It's your emotional anchor. Knowing that number means you can frame decisions clearly: "If price is above breakeven and my plan says take partial profit, I do it. If it's below, I assess whether my thesis still holds."

Example: You buy 2.5 SOL at $160 with $5 total fees. Your breakeven is (160Γ—2.5 + 5)/2.5 = $162. If price is $170, you have room to scale out. If price is $158, you're under breakeven, but perhaps your stop is at $152 because that's where your idea is invalidated. Notice how this keeps actions rational rather than reactive.

Keep breakeven in your journal for each trade. A simple spreadsheet with date, symbol, size, breakeven, stops, and targets can radically improve discipline. Your future self will thank you.

4 Position Sizing with the 1-2% Rule

Survival first. Edge compounds with small risks.

Position sizing is the heart of risk management. The 1-2% rule means you risk at most 1-2% of your account on any single idea. With a $4,000 account and 1% risk, the maximum loss per trade is $40. If your entry is $22 and your stop is $20, you risk $2 per coin, so your size is $40 Γ· $2 = 20 coins. If that feels small, that's the point. Survival is the first objective.

When volatility is high, consider risking even less (0.5-0.8%). You'll save mental energy and avoid the "all-in or nothing" spiral. Over time, steady small risks compound better than the occasional huge bet that jeopardizes the account.

  • Define your stop before entry. Moving it after you're in usually ends poorly.
  • Use smaller risk on lower-conviction ideas; size up only when multiple signals align.

5 Converting USD ⇄ Crypto for Planning

Translate your goals into concrete numbers.

Conversions help you translate goals into concrete numbers. If your plan is to allocate $250 to SOL each month, the converter tells you how many coins that buys at the live price. Likewise, if you hold 0.15 BTC and want to know its USD value right now, it's one click away. This keeps your planning precise and your expectations realistic.

Many investors underestimate how motivating small, consistent conversions can be. Seeing your holdings translate to a clear dollar value encourages steady habits that beat sporadic, emotional decisions.

6 Target Price from a Dollar Goal

Turn wishes into executable orders.

Instead of saying "I hope it pumps," choose a dollar goal and compute the exact sell price needed. If you own 0.35 ETH at $2,400 and want $300 profit, the tool gives you the sell price that will achieve that, factoring quantity and fees. This transforms wishes into actionable orders and eliminates hesitation when price reaches your objective.

Taking partial profits is often healthier than chasing the last cent. You can scale out at multiple targets while leaving a small runner in case momentum continues. Plans remove regret.

7 Fees: The Silent PnL Killer

Track spreads, taker fees, withdrawals.

Fees seem tiny, but they add friction to every trade. Spreads, taker fees, withdrawal costs all quietly reduce edge. Mitigate them by avoiding over-trading, consolidating orders when practical, and preferring limit orders on liquid markets. The calculator helps by letting you include estimated fees in advance.

For frequent traders, a fee-saving tier or a more efficient venue can make a real difference by year-end. Track it; what gets measured gets managed.

8 Taxes 101 (Orientation Only)

Keep simple records to avoid surprises.

Most places tax realized gains when you sell or swap. Keep consistent records: transaction dates, amounts, fiat value at the time, and fees. Export CSVs from exchanges monthly so year-end is easy. If you're unsure how your country treats staking, airdrops, or frequent trading, look up local guidance or talk to a professional.

The goal isn't to become a tax expert. It's to avoid surprises. A little organization now prevents stress later.

9 Security Basics You Must Not Skip

2FA (app), unique passwords, hardware wallets.

Security is non-negotiable. Enable 2FA via an authenticator app (not SMS), use unique passwords, and consider a hardware wallet for long-term holds. Be skeptical of unsolicited DMs and "support" messages. Double-check URLs before logging in; phishing is common.

Save your seed phrase offline. If anyone asks for it, it's a scam. Treat security as part of the investment, not an afterthought.

10 Psychology & Process

Consistency > prediction.

Success comes from boring consistency: define your setup, write your plan, execute it, and review results. If you feel FOMO, reduce size or skip the trade entirely. Waiting for high-quality setups keeps you available for the best opportunities.

A simple journal entry per trade (thesis, entry, stop, targets, and post-trade notes) will improve your decision-making faster than any indicator.

11 Case Study: Turning a Plan into Numbers

Combine our tools for end-to-end execution.

Imagine you buy 0.75 SOL at $160 with $2 in fees. Your plan: take 25% profits at +10%, another 25% at +20%, stop at $148. Using the Position Size tool ensures your dollar risk is fixed; the Target tool gives precise sell prices; the P/L calculator verifies outcomes. This removes guesswork and lets you focus on execution.

Write the plan before clicking buy. If you can't write it, you probably shouldn't take the trade.

12 Quick Checklist Before Any Trade

Five questions that keep you sane.
  • Do I know my thesis and what invalidates it?
  • Is my risk per trade ≀ 1–2%?
  • Are entry, stop, and targets defined?
  • Have I included fees in my plan?
  • Will I log this trade after?

If any answer is "no", pause. The market will still be there tomorrow. Discipline is the edge most people ignore.
