Coinmate is a Czech exchange and conversion platform whose company history dates its beginnings to 2014. It is operated by COINMATE a.s., registration number 14071711. Besides matching buy and sell orders, it provides custody: it can hold purchased crypto-assets for a client until they are withdrawn.
If you want to buy bitcoin with Czech koruna, you can begin with the simple Quick Buy interface. Advanced trading instead shows buyers’ and sellers’ offers in an order book. COINMATE a.s. terms distinguish the trading platform, a separate Exchange service, custody and transfers. This matters particularly when buying other crypto-assets: some marked assets have different sending rules. Being able to buy something does not, by itself, tell you whether you can send it to your own wallet in the usual way. [1] [8]
A Limit order says, for example: buy, but pay no more than the price I set. When selling, it sets the lowest acceptable price. It does not guarantee execution, because a suitable counteroffer must exist. Market takes available offers without a price limit specified by you; a larger order may use offers at different prices. The outcome can therefore differ from the reference price on screen. If only part of the trade executes, you can cancel the remaining unfilled portion. Acceptance of an order does not yet mean a completed purchase. [2]
The fee schedule describes Quick Buy as having no separate transaction fee. Its cost is nevertheless built into the quote through the spread, a price difference that includes service costs and the provider’s margin. To compare, look at the total koruna paid and the BTC actually received after applicable fees, including any withdrawal. In advanced trading, a maker adds an offer to the book while a taker uses an available offer. They add or remove liquidity, meaning offers available for trading. The fee rate also depends on your trading volume over 30 days. [3]
Recurring Buy can follow a standing order from your bank account. The rules require a correctly identified koruna payment and specify purchase within 24 hours of receiving the money when the conditions are met. A standing order determines how much money you send, not the future bitcoin price. After the trade, the exchange updates its internal records. This is called off-chain settlement because it does not record a transaction on the blockchain. That credit is not itself a withdrawal; moving bitcoin to your own wallet takes another step. [2]
Private keys authorize bitcoin to be spent. Coinmate’s rules describe Fireblocks MPC, where two of three separate shares participate in signing without assembling the whole key in one place. Hot, warm and cold wallets have different access arrangements for everyday operations or longer-term storage. The phrase self-custody wallet here means keys managed by Coinmate, not the customer. Even with separate records for each client, assets can be pooled on the blockchain. An account balance is therefore not your own authority to sign transactions. [4]
For marked assets in the Exchange service, the rules name another custodian, Payward Europe Solutions Limited. Ordinary automatic external transfers are not supported for those assets. A client can request a manual withdrawal, which involves checking ownership of the destination wallet and an administrative fee. The document states an average of 7 days and a maximum of 30 days, with exceptions for technical problems not attributable to the company. The scope matters: this is not a general deadline for every bitcoin withdrawal. The particular asset and service designation determine which rules apply. [4]
A transfer requires a supported asset, the correct network and the required sender and recipient information. Checks, limits or missing information can delay or stop it. A deposit address in your account helps the exchange credit incoming funds to you; it does not give you the private key for that address. When withdrawing into personal custody, check actual receipt in your own wallet. This distinguishes a request submitted to the exchange from bitcoin you can already manage yourself. [5]
More advanced users can use an API, an interface through which their software communicates with the exchange. Official examples distinguish reading prices, placing orders, viewing history and withdrawing. An assigned order ID identifies the order; it does not prove the whole order has filled. Coinmate Prime offers another approach: large trades with personal service and a stated minimum of CZK 5 million or EUR 200,000. Neither software nor a personal specialist bypasses pricing, identification or settlement conditions. It changes how the service is delivered, not whether the outcome is guaranteed. [6] [7]
