PHow to Buy POSX
Every exchange we track that lists POSX, what the buy costs, and what it costs to take POSX with you afterwards.
2 of the exchanges we track list POSX, and 2 of those accept fiat, so you can buy it without holding crypto first. The cheapest place to place the order is BitMart at $1.00 on a $1,000 market buy. POSX has no market-cap listing, so nobody publishes a dollar price we could convert the withdrawal fee into — the cheapest exit we can see is 21.6 POSX on XT.COM over Ethereum (ERC20), charged in the coin itself. POSX moves over 2 networks (BNB Smart Chain (BEP20), Ethereum (ERC20)) — pick the same one on the exchange withdrawal screen and in your wallet.

Where to buy POSX
POSX has no market-cap listing we can price it from, so the exit fee is shown in POSX itself rather than in dollars — the amount each exchange deducts when you withdraw. It is still the number that decides where to buy, because it is flat: the smaller your purchase, the more of it the fee eats. The coins column is how many assets each exchange lists in total, from our own sync — not the figure CoinMarketCap prints.

Buying POSX step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 2 exchanges list POSX at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 2 of those exchanges take fiat, 2 of them by card. Card is fastest and dearest; a bank transfer costs a fraction of it. Depositing a stablecoin you already hold is free on almost every exchange here.
- Place the order. A market order pays the taker fee in the table; a limit order that rests on the book pays the lower maker fee. On a thinly traded coin the spread costs more than either, so a limit order is worth the wait.
- Decide whether to move it. Leaving POSX on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee — send a small test amount first, and match the network on both sides.
How to buy POSX — FAQ
Where can I buy POSX?
On 2 exchanges we track: BitMart, XT.COM. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw POSX.
What is the cheapest way to buy POSX?
We cannot put a dollar figure on it: POSX has no market-cap listing, so there is no price to convert its withdrawal fee into. What we can compare is the two halves separately — the lowest trading fee is $1.00 per $1,000 at BitMart, and the cheapest withdrawal is 21.6 POSX at XT.COM over Ethereum (ERC20). Work out which matters more from the size of your buy.
Can I buy POSX with a credit card?
Indirectly, yes. 2 of the exchanges listing POSX accept a card (BitMart, XT.COM), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for POSX on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Do I have to pay a fee to withdraw POSX?
Every exchange charges one, as a flat amount of POSX per network rather than a percentage. We do not have a priced figure for all of the venues listing POSX yet — the POSX withdrawal fee page has whatever each exchange publishes.
Is it safe to leave POSX on the exchange?
It is a custody choice, not a safety switch. While the coin sits there the exchange holds the keys: convenient, recoverable if you lose your password, and dependent on the exchange staying solvent and keeping withdrawals open. Moving it to a wallet you control removes that dependency and costs one withdrawal fee. For a trading balance, staying put is reasonable; for a long hold, most people move.
Which network should I use for POSX?
POSX is issued on 2 networks and they are not interchangeable — POSX sent over BNB Smart Chain (BEP20) will not arrive at an address on Ethereum (ERC20). BNB Smart Chain (BEP20) is the one most exchanges use (1 of them). Withdrawal fees differ per network too, sometimes by an order of magnitude, so the cheapest network is worth checking as well as the cheapest exchange.
A note on this page: POSX is a ticker the exchanges below list and settle, but it has no CoinMarketCap listing, so there is no price, market cap or rank to show and no coin page for it elsewhere on this site. Tickers are not unique across exchanges either — confirm on the exchange itself that its POSX is the asset you mean, and check the contract address before you send anything.
Exchange coverage for POSX comes from each exchange’s own deposit and withdrawal endpoints (last sync 2026-08-29 00:53 UTC); trading fees are the published base tier, no volume discount applied. Exchanges we have a referral arrangement with appear first and are tagged as such — it changes no number in any row. Nothing here is investment advice; see our methodology.
