Short answer: You can buy and sell crypto in almost any country using a crypto exchange, a peer-to-peer (P2P) marketplace, a payment app, or a crypto ATM. Which one fits depends on your local payment methods, the fees, and whether you want to keep control of your crypto. But here's the part most guides miss: the goal isn't to buy crypto and watch it sit, it's to use it. And the smartest way to do that often means not selling at all.
The ways to buy and sell crypto
- Crypto exchanges (Coinbase, Binance, Kraken). Buy with a bank transfer or card and sell back to your local currency. They're the most common route and beginner-friendly, but availability varies by country, and they're custodial, meaning the exchange holds your crypto until you withdraw it.
- Peer-to-peer (P2P) marketplaces. Trade directly with other people using local payment methods like bank transfer, mobile money, even cash. P2P reaches countries where exchanges don't operate. Use escrow and trade only with reputable counterparties.
- Payment and broker apps. Apps you may already use, like PayPal, Cash App, Revolut, and regional equivalents, let you buy crypto in a few taps. Convenient, but many limit whether you can move that crypto out to a wallet you control.
- Crypto ATMs. Buy or sell with cash in person. Handy where they exist, but fees are usually high, so check the rate before you commit.
What to check before you buy or sell
- Local payment methods: does it support your bank, card, or mobile money?
- Fees: the buy/sell fee, the exchange-rate spread, and anything added on top.
- KYC: most regulated services require identity verification.
- Custody: do you keep your keys, or does a company hold your crypto?
- What you can do next: can you actually use it (pay, earn, send), or only hold it?
That last point is where the real value lives. Buying crypto is the easy part. Being able to use it in everyday life, anywhere, without giving up control, is the hard part most tools never solve.
The part most guides skip: using your crypto
For most people, crypto gets bought and then just sits on an exchange, in someone else's custody, doing nothing, until they sell it back and pay fees on the way out. Selling to a bank is slow, sometimes taxable, and fee-heavy.
There's a better path: bring the crypto you own into a self-custodial account where it becomes money you can actually live on while it stays yours the whole time. That's what Tria is built for.
How Tria makes your crypto usable almost anywhere
Tria is a self-custodial neofinance app. You bring the crypto you already hold into a wallet you control, and Tria turns it into something you can use across 150+ countries without ever handing over your keys.
- Pay with it, anywhere Visa works. The Tria Card draws from your own balance at 130M+ merchants across 150+ countries, with up to 6% cashback and Apple Pay / Google Pay. You often never need to sell at all, you just pay, and the card converts what you need at the moment of purchase.
- Grow it while it waits. Idle balance can earn up to 15% APY through on-chain protocols, so your crypto works even when you aren't using it.
- Move it across 200+ chains. Swap between chains with BestPath routing, with no manual bridging.
- Trade it self-custodially. Trade perpetual futures through integrated venues (Hyperliquid and Decibel), from the same balance.
Everything runs from one self-custodial account: your keys, your crypto, right up to the second you pay. That's the difference between owning crypto and just parking it on a platform.
Frequently asked questions
Can I buy crypto in any country?
Almost. Between exchanges, P2P marketplaces, payment apps, and ATMs, crypto is buyable in the large majority of countries. What changes is which method works where you live and which local payment options are supported.
What's the cheapest way to buy and sell crypto?
Look at two costs together: the buy/sell fee and the exchange-rate spread. A local bank transfer is often cheapest; cards and ATMs are faster but usually cost more.
Do I need to sell my crypto to use it?
Often, no. With a self-custodial card like Tria's, you can pay directly from your own balance at any merchant that accepts Visa, and the card converts what's needed at checkout, so you use your crypto without cashing out to a bank first.
Can I keep custody of my crypto and still use it?
Yes. A self-custodial app like Tria keeps your keys with you and still lets you pay, earn, swap, and trade. Your crypto is only ever used at the moment you transact, and it's never held by a company.
