Learning track

Crypto and international payments

Somebody in Iran working with a client abroad usually hits a wall on day one: the work is delivered and there is no simple way to be paid for it. This path takes that wall apart, not by telling you what to buy, but by explaining exactly what each tool does and where it stops working.

Four stations, in the order you actually need them

It starts with understanding and ends at a real payment. Skipping the third station is where people lose their money.

  1. 1

    Understanding

    What a cryptocurrency is and how a blockchain works. Without these two the rest is memorising a few words.

  2. 2

    The stable tool

    The stablecoin, because somebody collecting a fee is not after volatility, they are after the agreed amount.

  3. 3

    Keeping it

    Wallets and security. Unlike a bank, there is no number here you can call to have a transfer reversed.

  4. 4

    The real payment

    The networks and their fees, international payment from Iran, and the virtual card for when the other side takes only a card.

These four are a learning order, not a formal taxonomy. Even somebody who only wants to be paid once cannot skip the third station, because a mistake there does not come back.

The path, step by step

Lessons are ordered so each stands on the previous one. You can also jump in anywhere.

  1. 1What a cryptocurrency actually isA cryptocurrency is not something stored on your phone; it is a row in a ledger that thousands of independent computers each keep a copy of, and owning it means holding the private key that can authorise moving that row. The same two properties that make this work, no institution in the middle and no way to reverse a transfer, are both its biggest advantage and its biggest danger.Beginner
  2. 2How a blockchain actually worksA blockchain is a shared ledger that writes transactions in batches called blocks, and every block carries the digital fingerprint of the block before it inside itself. That single rule makes changing an old row require rebuilding everything that came after it, and it solves a problem that had not been solved before: agreeing on one single order with nobody in charge.Beginner
  3. 3What stablecoins and Tether areA stablecoin is a cryptocurrency whose price is deliberately held still, almost always at one dollar, and behind that stillness stands a company saying it holds a dollar of assets for every token. That is why work gets settled in Tether rather than Bitcoin: the price movement is taken out of the payment, while the risk is not removed at all, only moved from the market to the issuer.Beginner
  4. 4Crypto walletsA crypto wallet does not hold money; it holds the key that signs a transfer, and the asset itself always sits on the network. That is why the first choice is not between hot and cold: it is whether that key is in your hands or in the hands of a company that gave you an account.Beginner
  5. 5Crypto security and crypto scamsA crypto payment has no undo button: a transaction that has settled on the network does not come back, and no authority exists to bring it back. Nearly every habit in this lesson comes out of that single property, and any advice that does not take it seriously is worthless.Beginner
  6. 6Transfer networks and feesA coin usually exists on several separate networks, and the same name with the same logo is a different ledger on each one, so the sender and the receiver have to pick exactly the same network. The fee has nothing to do with how much you send: each network charges for the space you occupy or the computation you cause, and the price moves with congestion at that moment.Intermediate
  7. 7Paying an international service from IranThere are usually five workable routes for paying a foreign service from Iran, and what decides between them is not price but who owns the account when you are finished. The shortest route is wherever the service itself sells crypto payment or prepaid credit; every other route adds an intermediary, and each intermediary carries one specific risk that can be named.Beginner

Two things up front, because the whole path is built on them. First, this is education and not investment advice: no lesson tells you what to buy, when to buy it, or what a price will do, and if you ever read that here we got it wrong. Second, the legal status of crypto activities differs from one country to another, and within a single country it changes. We are not lawyers and we make no legal claim; the rule that applies to you today is one you have to check today.

The lessons run from the concept to the work. The first two say what you are actually dealing with: what a cryptocurrency is and how a blockchain works. Then comes the thing people actually transact in, the stablecoin, and after it the wallet and the security that decide whether your money stays yours. The last four are practical: the networks and what they cost, international payment from Iran, and the virtual card.

One thing this path does not do, better said here than discovered later. No lesson writes a way around a law, a way to hide who you are, or a way past somebody restriction. We recommend no particular exchange, and we invent no rate and no fee; every number you meet in this path comes either from that network own documentation or from our own payment system, whose code sits on this server.

Real follow-up questions

Does this path tell me which coin to buy?

No, and that is a policy rather than an oversight. We are a web agency, not financial advisers; what we know is how a payment works, not what happens tomorrow. If you are after an investment decision this is the wrong path, and we do not write that.

Is working with cryptocurrency legal?

The answer differs by country and does not stay put inside one either; one activity may be permitted, another may need a licence and a third may be forbidden. We are not lawyers and we give no legal opinion here. The rule where you are today has to come from an official source there, and for anything serious, from a lawyer.

Do I have to learn crypto to be paid by a client abroad?

No. Crypto is one route among several and each has its own cost and its own friction; the last two lessons of this path cover the other routes and the virtual card. One thing to know though: whichever route you pick, the other side has to accept it too, and that constraint usually makes the choice for you.

This path is written for somebody who wants to understand payment and choose for themselves. If crossing a border is the whole problem, one route that removes it entirely is domestic work, and See the RGB freelance marketplace
