I’m thinking about using the Coinin app for managing my crypto, but I’ve seen mixed opinions online and I’m worried about security, fees, and reliability. Can anyone share real user reviews, issues you’ve faced, and whether you’d still recommend Coinin today so I can decide if it’s safe to trust with my funds?
Used Coinin for about 7 months. Mixed bag. Here is the blunt version so you know what you are walking into.
- Security
- App asks for email, phone, and KYC pretty early.
- 2FA works, but sometimes SMS codes arrive late. I switched to an authenticator app, much more stable.
- Had 2 login alerts from unknown IPs. Password + 2FA held up, no funds lost. Support said it was “routine scanning”. I moved most funds off after that.
- I now treat Coinin as a hot wallet / trading front only. Main stack sits on a hardware wallet.
- Fees
- Trading fees are mid tier. Not the worst, not the best. Around 0.2 percent for spot unless your volume is high.
- Spreads get ugly on low volume pairs. On majors like BTC, ETH, USDT pairs it is fine.
- Withdrawal fees are on the higher side for some coins. Check their fee page for each asset before you fund. For BTC and ERC20 tokens it stung a bit.
- They run promo fee discounts, but they are temporary and usually on niche coins.
- Reliability and performance
- App UI is simple, no clutter, but a bit laggy on older phones. Android runs smoother than iOS from what I saw.
- During high volatility, order execution sometimes freezes for a few seconds. Had a limit order on BTC take 10 to 15 seconds to show as filled even though the price passed through. Not great if you scalp.
- Had one incident where balance displayed as zero for about 3 minutes, then refreshed back to normal. Support said it was a “cache issue”. I was not amused.
- Withdrawals:
• On-chain BTC and ETH withdrawals took 5 to 20 minutes on normal days.
• One USDT withdrawal stuck “processing” for 2 hours, then went through. No funds lost, but no clear explanation.
- Support
- Response time through in-app chat was 4 to 12 hours on average for me.
- Answers felt canned at first. If you push and ask specific questions, they do answer, but it takes longer.
- No phone support. Only chat and email.
- Liquidity and coins
- Large caps have ok liquidity. Slippage was low on BTC and ETH with order sizes under 5k.
- Small caps are risky on there. Thin books and fast swings. If you trade those, use limit orders, not market.
- Some tokens get listed, run for a bit, then volume dies. If you plan to move coins to another exchange, check that they are supported elsewhere before you buy.
- Things that annoyed me
- Occasional random logouts. You open the app, it kicks you back to login. Annoying.
- Price alerts delayed. I set alerts at key levels and sometimes the alert hit 1 to 2 minutes late.
- Their promo banners get pushed hard in the app. Turn off marketing notifications if you sign up.
- Things that worked fine
- Internal transfers between Coinin users were fast and cheap. I used that twice with a friend.
- Fiat onramp through card worked, but fees were higher than using a bank transfer to a bigger exchange then sending crypto in.
- Basic spot trading is simple enough for a beginner. Order book and charts are clean.
Practical advice if you go ahead
- Do not park large holdings there. Use it as a tool, not a vault.
- Turn on 2FA with an authenticator app, not SMS.
- Test with a tiny deposit and withdrawal first, see processing times for your country and bank.
- Read their status or social channels when markets are wild. If they have outages, people complain there first.
- Compare their BTC and ETH spreads and fees with one big exchange before you move serious size.
If your top priority is security and long term storage, use a hardware wallet and maybe a more battle tested exchange for bigger trades.
If you want a simple app to do small trades and you are ok with some hiccups, Coinin is workable, but you need to manage your risk and expectations.
Used Coinin on and off for about a year, mostly small‑mid size amounts, so here’s the non-glossy version.
I broadly agree with @byteguru, but I’m a bit less forgiving on some parts and a bit more chill on others.
Security & trust vibes
- KYC: They’re pretty aggressive with KYC & re-verification. I had to re-upload docs after ~6 months because of some “policy update”. Annoying, but not shady by itself.
- 2FA: Authenticator app worked fine for me, no major delays. I actually never had the weird login alerts they mentioned, so that might be region or timing dependent.
- Custody: I would not treat it as your main bank. Hot wallet behavior, exchange-style risk. I kept no more than a couple thousand on there at any given time.
- Red flag for me: they’re not super transparent about where funds are custodied or any insurance. If they said “we partner with X custodian, here’s our audit,” I’d feel way better.
Fees in practice
- Trading: mid-range, yep. You can find cheaper, but you’re not getting totally robbed.
- Hidden cost is spread on some pairs. On majors I found it acceptable, similar to what @byteguru saw. On some random alt I tried, slippage was bad even with limit orders because books were thin.
- Withdrawal fees felt like they’re optimized for their profit, not user convenience. I started using cheaper networks (e.g. non-ERC20 versions) whenever possible. Check network options carefully before moving stablecoins.
- Fiat fees: card deposits were painful. I ended up doing fiat in on a bigger exchange, then transferring crypto into Coinin if I really needed to trade there.
Reliability & performance
Here’s where I’m a bit harsher than @byteguru.
- App stability was “ok” on Android, but iOS felt janky for me. Two hard crashes during order placement over a few months is two too many.
- Orderbook refresh lagged during heavy volatility. If you’re doing anything faster than swing trading, this is not where you want to be.
- I also had the “balance shows 0” bug once. That’s the single most heart attack inducing bug an exchange can have. Even if it is caching, that should never ship to prod.
Support & communication
- Support response time: similar experience, half a day-ish.
- Where I disagree a bit with @byteguru is that I never got truly detailed answers. Even when I pushed, the replies stayed vague. “We are experiencing high traffic” was the magic phrase for every issue.
- Their status / announcement behavior is mediocre. Stuff breaks first, then they acknowledge. I prefer platforms that scream up front: “We’re throttling withdrawals, expect delays.”
Coins, liquidity & actual use case
- Liquidity on majors is fine for regular humans. If you’re moving 4 or 5 figures, you’ll be okay on BTC/ETH pairs most of the time.
- On low-cap stuff, I’d argue Coinin is worse than some of the bigger exchanges. Thin orderbooks plus retail-focused crowd = easy to get trapped if you buy something that later gets no external listings.
- I used it as a place to grab a couple of niche tokens early, then moved them out to a different exchange or wallet once possible. Treat new listings as “high risk, exit strategy required”.
Random annoyances
- Forced marketing: same as mentioned, but I’d add that some promos feel borderline misleading if you don’t read the fine print (volume requirements, lockups, etc).
- App UX: actually not terrible, but there are small things like order history loading slow or filters resetting that give it a “B-tier” feel instead of polished.
Who is Coinin for (in my opinion)
- Reasonable use:
- Small to medium trades.
- Grabbing a specific coin that your main exchange does not list.
- Testing strategies you’re not comfortable running with your main stack.
- Not great for:
- Long-term storage.
- High frequency trading.
- People who panic easily when balances glitch or withdrawals slow.
If you’re on the fence
- Open the account, KYC, but start tiny. Like “coffee money” tiny.
- Do 1 deposit, 1 trade, 1 withdrawal. Time everything.
- Compare your effective cost (fees + spread) to 1 or 2 major exchanges you already trust.
- If during that test you already hit bugs, delayed support, or sketchy UX, just stop there. Exchanges don’t get magically better under stress, they get worse.
TL;DR: It’s not a total scammy dumpster fire, but it’s also not in the “park my life savings here” category. Treat it as a secondary tool in your kit, not your primary home for crypto.
Coinin is basically a “usable but not core” app in the current crypto stack.
Where I slightly disagree with @boswandelaar and @byteguru is on how scary some of the glitches are. A 2‑hour “processing” withdrawal or a 3‑minute zero balance screen is unacceptable for primary storage, but not unusual on second‑tier exchanges. That is the category I’d put Coinin in.
Pros of Coinin app (from what you’d actually feel as a user)
- Simple UI, very low learning curve for spot trading
- BTC/ETH/USDT pairs are liquid enough for normal retail sizes
- Internal transfers and small withdrawals generally complete without drama
- Authenticator‑based 2FA works reliably if you set it up correctly
- Decent place to grab niche coins your main exchange does not list
Cons of Coinin app
- Hot‑wallet style custody, no clear public proof of reserves or insurance details
- App stability feels “B‑grade,” especially during wild markets
- Withdrawal fees on some networks are clearly profit‑tuned
- Support is slow to acknowledge issues and sticks to generic wording
- Marketing promos inside the app are pushy and sometimes confusing
Compared with what @boswandelaar and @byteguru wrote, I’d say they are slightly too harsh on fees and slightly too forgiving on transparency. You can live with mid‑tier fees. Lack of rock‑solid public audits is the bigger long‑term concern.
If you do try Coinin for managing your crypto:
- Treat it as a trading front end, not as a vault
- Keep your long‑term stack on a hardware wallet or a more established exchange
- Test every path you plan to rely on: one small fiat in, one small trade, one small withdrawal, then scale only if you like the behavior
Realistically, Coinin makes sense as a secondary app beside a bigger player, not as the center of your setup.
