How to Buy and Sell Crypto in Vietnam Without an Exchange Account (2026)
Buy crypto with fiat and cash out to your bank from one app you control, no separate exchange account needed.
Getting in and out of crypto used to mean a choice between two uncomfortable options. Either you met a stranger from a chat group with an envelope of cash and hoped it was not a scam, or you ran the full marathon of signing up to a separate exchange, waiting days for verification, and wiring money you hoped would actually arrive. Both cost time, and both carry a knot in your stomach.
There is a simpler path now. You can buy crypto with fiat and cash it back out to your bank from inside one app, from a wallet you control, without a separate exchange account. Here is how in-app P2P works.

The over-the-counter route is fast but risky: no recourse if the cash is fake or the transfer never lands. The exchange route is safer but slow: an account to open, documents to submit, and a waiting game before you can move a single dollar. For a traveler who just wants spending money ready, neither is a good fit.
In-app P2P: buy and sell without a separate exchange
Fizen has P2P built in, so buying and cashing out happen where your money already lives.
- To buy: open Fizen P2P, enter a fiat amount, accept the terms, and send the bank transfer using the details shown.
- To sell: choose Sell, enter the crypto amount, pick the bank account to receive funds, and confirm. The fiat is credited once the transfer is verified.
- One tip: copy the transfer details exactly as shown, since any error can cause a loss of funds.
That is the whole loop. Load up before a trip, and cash out whatever you do not spend when you get home, without a second app or a bank branch.
Swap between tokens for the best rate
Already holding crypto and want to move between tokens? The in-app swap, currently on Android, routes through the KyberSwap and 1inch aggregators, which pool rates across many exchanges so you get the best available price without hopping between platforms.
One setup, your whole trip sorted: the Fizen Super App
This is where Fizen stops being a single-purpose tool and becomes your travel command center. From the same balance and the same few-minute setup, you get a lot more than one feature.
Pay by QR, and tap a Visa card
Scan VietQR like a local, and let the same balance power a virtual or physical Visa card for everything without a QR code: flights, hotels, and online checkouts anywhere Visa is accepted.
Get online the moment you land
Buy a travel eSIM inside the app. Open the eSIM section, search your destination, choose a plan by validity and daily data, pay, and activate before you fly. No airport SIM kiosk, no roaming bill.
Buy and sell crypto without leaving the app
Built-in P2P lets you buy crypto with fiat or cash out crypto to your bank, and the in-app swap, currently on Android, routes through the KyberSwap and 1inch aggregators for the best available rate.
Cashback that comes back as something you keep
Most cards give you a small discount and call it cashback. Fizen gives you a choice. Card spending earns rewards you can take as gift cards, USDT, or the $FIZEN token, whichever you prefer, and the earlier you start, the more of it the same spend earns.
And more from the same balance
Top up a phone, grab a gift card, book hotels and flights, or invest in tokenized U.S. stocks, T-bills, and ETFs. One account does the job of a wallet, a card, a SIM shop, an exchange, and a rewards program.
Own the bank, do not just rent an app
A neobank hands you an account and holds your money for you. Fizen flips that. Your balance sits in USDT, a dollar-pegged stablecoin, in a wallet you control. Your money, your keys, your call. No branch can freeze your trip on a public holiday, and no teller decides your rate.
You are not a customer waiting in a queue. You hold the balance, you move it, you spend it by QR or card, and you cash it out when you want. Freedom and control, in your pocket, before you even pack. Fizen is backed by Tether, the issuer of USDT, and verifies your identity once during setup.
