One irreversible field

An account holds one currency, and picks it once (South Africa)

Comparisons of account types usually run on trading conditions. From the money side there is a plainer question: which choices on that creation screen can be revisited, and which one closes behind you. Exactly one closes — the currency the account is held in.

The account's base currency is fixed at creation. The creation screen lists the options available for the type being opened, and from that point every figure on the account — the balance, the margin held, the result of a closed trade — is counted in it. A payment sent in rand into an account held in another currency is converted into that currency by the payment provider on the way in. That single field therefore decides whether money crosses a currency on every deposit and again on every withdrawal.

What the creation screen settles, and for how long

Sorted by whether a later decision can undo it.

Field	Reversible?	What it governs afterwards
Base currency	No — fixed at creation	What every figure is counted in, and whether a rand payment is converted
Account type	By opening another account instead	The trading conditions and the minimum shown at sign-up
Platform	Yes	Which terminal you sign in with — the money lines read the same on each
Nickname or label	Yes	Nothing about the money; it only helps you tell accounts apart

Because only one row says no, the rest of the screen deserves less deliberation than people give it, and that row deserves more.

A second account is the way to change your mind

Nothing about a fixed currency traps you. It simply means the answer to I picked the wrong one is a new account rather than an edit to the old one, and a profile is built to hold plenty of them: up to 100 MT4 and 100 MT5 accounts, 200 in total, under a single login. A real and a demo MT5 Standard account are created automatically after sign-up, which is why many people find an account already waiting before they have chosen anything at all.

What does not transfer is the money already sitting on the old account. Moving it is an operation with its own screen, not a side effect of opening a new one, so the order to run is: open the new account first, look at what it is denominated in, then move.

What does transfer is your identity file. Verification belongs to the profile, not to a single trading account, so a second account does not restart the document check. What the document check covers

Naming accounts so you can tell them apart later

A profile that holds several accounts stops being readable within a month unless the labels do some work. Three habits are enough.

Put the currency in the label. It is the one attribute that cannot be corrected later, so it is the one worth reading at a glance from the account list.
Mark which are practice and which are live. Both kinds appear in the same list, both look the same in a screenshot, and only one of them holds anything.
Note the account number somewhere outside the platform. A question to a support desk about a specific account is far quicker to answer when it names which one.

An independent guide: it opens no accounts and sets no currency. The options available for each account type are shown on the creation screen inside your Exness account area.

What the account choice does not touch at all

Two things sit above the account list and are unaffected by anything chosen on a creation screen. The first is the identity file: it belongs to the profile, so a document accepted once covers every account opened under it, and no account type asks for a second check. The second is the sign-in itself — one login reaches all of them, with its own password, separate from the platform password each trading account carries.

Holding an account that is doing nothing carries no inactivity fee, so there is no pressure to close a currency you opened and stopped using. It can sit in the list, correctly labelled, until it is wanted again. What an account will not let you do yet

Questions about the fields on the creation screen

Can the account currency be changed after the account exists?

No. It is fixed at creation, and the way to hold a different one is to open another account.

Where do I see which currencies are available to me?

On the creation screen itself, which lists the options for the account type you are opening.

Does a second account mean a second identity check?

No. Verification sits with the profile, so a document accepted once covers the accounts opened under it.

How many accounts can one profile hold?

Up to 100 MT4 and 100 MT5 accounts, 200 in total, all reachable from one login.

Is money moved automatically when I open a new account?

No. A new account starts empty; moving funds between accounts is a separate operation with its own screen.

Does the account type change how a withdrawal is paid?

The rule is the same across types: money up to the amount deposited returns to the original method, with anything above that paid out separately.

Is the stated minimum the amount I should start with?

It states what will be accepted, nothing more. What suits you is a separate decision that no screen makes.

Does an idle account cost anything?

There is no inactivity fee. An account can sit unused without charges accumulating on it.
