How to Buy Rubic (RBC)
Every exchange we track that lists RBC, what the buy costs, and what it costs to take RBC with you afterwards.
4 of the exchanges we track list RBC, and 4 of those accept fiat, so you can buy it without holding crypto first. The cheapest place to place the order is MEXC at $0.50 on a $1,000 market buy. But add the fee to move RBC off the exchange and the order changes: Gate comes out lowest at $1.47 all-in, against $3.71 on the cheapest trading fee. The withdrawal fee is flat, so the smaller your buy, the more it decides where you should buy. Every exchange sends RBC over Ethereum (ERC20), so there is no network to get wrong.

Where to buy RBC
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw RBC. It is the number the exchange’s own “how to buy” page never shows you, and it reorders the table more often than not. The coins column is how many assets each exchange lists in total, from our own sync — not the figure CoinMarketCap prints.

Buying RBC step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 4 exchanges list RBC at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 4 of those exchanges take fiat, 3 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 RBC on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee, from $0.4748 — send a small test amount first, and match the network on both sides.
How to buy RBC — FAQ
Where can I buy Rubic (RBC)?
On 4 exchanges we track: Gate, MEXC, CoinEx, Kraken. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw RBC.
What is the cheapest way to buy RBC?
Gate, at $1.47 to buy $1,000 of RBC and withdraw it — $1.00 in trading fee plus $0.4748 to move it out over Ethereum (ERC20). If you are leaving the coin on the exchange, only the first half applies and a different venue may win. Paying by card adds the card processor's charge on top of both, typically 1.8–4%.
Can I buy RBC with a credit card?
Indirectly, yes. 3 of the exchanges listing RBC accept a card (Gate, MEXC, Kraken), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for RBC 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 RBC?
Yes, and it is worth checking before you choose where to buy. It is a flat amount of RBC, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $0.4748 on Gate. Our full RBC withdrawal fee table compares every exchange and every network.
Is it safe to leave RBC 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 — from $0.4748 for RBC. For a trading balance, staying put is reasonable; for a long hold, most people move.
