A few years ago, a guy I know sent ₹40,000 worth of USDT to a friend and watched it vanish. Not stolen, not hacked — he just sent it on the wrong network. The wallet on the other end simply didn't recognize the deposit, and that was that. No bank to call, no dispute form, no refund. Just gone.
That's the part about crypto nobody really explains to you upfront: there's no undo button. Once a transaction is confirmed on the blockchain, it's final, whether you meant to send it or not, whether the address was right or off by one character.
Most people who lose funds this way aren't careless they're just new, and nobody walked them through the basics first. So here's that walkthrough.
At the core, it's just moving digital assets - Bitcoin, Ethereum, stablecoins, whatever from one wallet address to another on a blockchain.
Think of a wallet address like an account number, except there's no bank sitting behind it verifying anything. You share your address to receive funds. You type (or better, paste) someone else's address to send funds. That's it. There's no institution checking whether the transaction "looks right" before it goes through which is exactly why it's on you to get it right the first time.
India's crypto user base has grown quickly, and a lot of that growth is first-time retail investors - people who've never had to think about network fees or wallet formats before. Blockchain analytics firms have pointed out repeatedly that most reported losses aren't from exchanges getting hacked. They're from ordinary user mistakes: wrong address, wrong network, rushed decisions.
There's also a compliance angle now. With TDS applying to crypto transactions in India, keeping accurate records of every transfer isn't optional bookkeeping anymore it's something you'll want for your own tax filing.
Before we get into steps, here's roughly what "doing it right" involves:
1. Pick a platform you actually trust. Whether that's an exchange like Koinpark or your own hardware wallet, don't cut corners here.
2. Check the recipient's address twice. Paste it, don't type it. If there's a QR code, scan it instead, it removes the human error entirely.
3. Confirm you've got the right network. USDT alone can move on TRC-20, ERC-20, or BEP-20, and they're not interchangeable. This single step causes more lost funds than almost anything else on this list.
4. Test first if it's a large amount. Send something small, confirm it arrived, then send the rest. Five extra minutes beats losing everything.
5. Check the fee before confirming. Fees move with network congestion — what you paid yesterday isn't necessarily what you'll pay today.
6. Authenticate. 2FA, biometrics, PIN — whatever your wallet uses, don't skip it.
7. Track it. Use a blockchain explorer to watch it move through confirmations instead of just hoping.
1. Generate your address. Open your wallet, hit "Receive," pick the right coin.
2. Tell the sender which network to use. Don't assume they know — say it explicitly.
3. Share the address or QR code. QR codes cut down on typos on their end too.
4. Verify it on-chain once they've sent it. Don't just take their word for it — check the explorer link.
5. Wait for confirmations. Most chains need a few before the funds are usable.
6. Move large amounts to cold storage if you're not planning to trade with them right away.
✔️Check at least the first and last four characters of any address before confirming
✔️Use an authenticator app for 2FA, not SMS — SIM-swap attacks are a real thing
✔️Whitelist withdrawal addresses wherever your exchange allows it
✔️Don't touch your wallet over public Wi-Fi
✔️Your seed phrase stays offline. Not in your notes app, not in a screenshot, not in the cloud
✔️Bookmark the real platform URL so you never land on a phishing clone by typo
✔️Keep your wallet app and device updated
❌Sending ERC-20 tokens to a TRC-20 address (the single most common one)
❌Typing addresses by hand instead of pasting or scanning
❌Ignoring fees and ending up with a stuck transaction
❌Giving out a seed phrase to anyone — including someone claiming to be "support"
❌Skipping the test transaction on a large transfer
❌Downloading wallet apps from somewhere other than the official app store
Someone I'll just call a Mumbai-based trader wanted to move USDT off an exchange into a personal wallet. He didn't check which network the destination wallet supported — just assumed USDT is USDT — and sent it over ERC-20 to an address that only accepted TRC-20 deposits.
The funds are still sitting there, technically, but the receiving wallet has no idea they exist. That's the whole risk in one sentence: it's not that the money gets stolen, it's that it becomes unreachable.
"Crypto is anonymous." Not really, most blockchains are public ledgers. Your transactions are pseudonymous, and with the right tools, traceable.
"If I mess up the address, support can fix it." No exchange or wallet, Koinpark included, has the power to reverse a confirmed blockchain transaction. That's not a policy choice — it's how technology works.
"Any wallet works with any network automatically." You have to pick the network yourself, every time. Nothing does this for you by default.
Before You Hit Send, Check:
☑ Full recipient address verified
☑ Correct network confirmed
☑ Fee checked
☑ 2FA is on
☑ Test transaction sent (for large transfers)
☑ Transaction hash saved somewhere
A note worth repeating: no legitimate platform, Koinpark included, will ever ask for your seed phrase over email, chat, or phone. If someone reaches out claiming to help "recover" a transaction or fix an "urgent account issue," that's not support — that's a phishing attempt.
Getting comfortable with this takes maybe one or two transactions of paying close attention. After that, it really does become second nature. The habits above aren't complicated — they just have to become automatic, because the blockchain doesn't give second chances.
What's the safest way to send and receive crypto?
Verify the recipient's address and network, use copy-paste or a QR code instead of typing manually, keep 2FA on, and test large transfers with a small amount first.
Can a crypto transaction be reversed if I send it to the wrong address?
No. Once it's confirmed on the blockchain, it's permanent — there's no mechanism to cancel or reverse it.
What happens if I send crypto on the wrong network?
If the receiving wallet doesn't support that network, the funds can become permanently inaccessible. Always match the network on both ends before sending.
Is it safe to receive crypto from someone I don't know?
Receiving itself is low-risk since it only requires your public address. Be wary of anything that follows — unsolicited "gifts" tied to links or requests for personal info are common bait.
Do I need to pay tax on crypto transactions in India?
Yes — gains are taxed at a flat rate, and TDS applies on transfers above certain thresholds. Keeping transaction records makes filing far less painful.
What's the difference between a hot wallet and a cold wallet?
A hot wallet stays connected to the internet and suits frequent, smaller transactions. A cold wallet stays offline and is better for holding larger amounts long-term.
How long does a crypto transaction take?
Anywhere from seconds to several minutes, depending on the blockchain and how congested it is. Higher fees can speed things up.
My transaction is stuck — what do I do?
Check the status with your transaction hash on a blockchain explorer. If it's stuck from a low fee, some wallets let you accelerate it; otherwise, you'll need to wait out the congestion
