This blog introduces you to a wonderful tool called Mempool.Space. Read on to understand why and how to use it:
✅ 1. Know When to Send Bitcoin (Fee Awareness)
Even if you don’t trade, you will occasionally send Bitcoin — from an exchange to your wallet, to a friend, to cold storage, or during inheritance planning.
Mempool.space helps you:
🔹 Avoid overpaying fees
You can check the “Next Block Fee” and see when the network is busy or quiet.
- If the fee is high → wait a few hours or a day.
- If it’s low → send now and save money.
For a common user, this alone can save hundreds or thousands of rupees over years.
✅ 2. Track Your Transaction (Peace of Mind)
When you send BTC, many people (especially new users) get anxious:
- “Is my money stuck?”
- “Has it gone through?”
- “When will it confirm?”
Instead of panicking or asking support, you can:
👉 Paste the transaction ID into mempool.space.
It will show:
- 📦 which block it may confirm in
- ⏳ estimated confirmation time
- 🟢 number of confirmations
- 🔥 whether the fee is too low or fine
This is pure peace of mind for a normal user.
✅ 3. Avoid Scams Using Explorer Verification
Scammers often send fake screenshots of “payment sent.”
But on mempool.space:
❗ If it’s not on the blockchain → it didn’t happen.
Just ask them for the TXID and paste it.
If there is no transaction, walk away.
This prevents the most common beginner scam.
✅ 4. Understand What’s Happening During Congestion
Sometimes you hear:
- "Bitcoin is slow today"
- "Fees shot up because of some craze"
- "Why is my transaction stuck?"
Most people get confused.
On mempool.space you instantly see:
- how full the mempool is
- why fees are high
- whether it's due to ordinals, Runes, ETF activity, etc.
This gives you context and eliminates unnecessary fear.
✅ 5. Learn the Basics of How Bitcoin Works (Visually)
Most common people learn visually, not technically.
mempool.space shows:
- how miners pick transactions
- how blocks get mined
- live blocks being added
- global map of miners
- hash rate changes
- even Lightning channels and fees
This helps a normal HODLer feel more confident and connected to the network.
✅ 6. Self-Verifiable Trust (No Need to Trust a Company)
Most people rely on:
❌ Coinbase
❌ Exchange wallets
❌ Apps that “tell” you your balance
❌ A third-party explorer
mempool.space is open-source and independent.
A common man can:
- verify a transaction without trusting a company
- check balances or confirmations in a neutral way
- see the final settlement on the chain
This aligns with Bitcoin’s core idea:
Don’t trust. Verify.
