Štosuj.cz is a Czech software tool that can, for example, repeat a purchase for a preset amount at regular intervals. The user chooses the rules and authorizes a connection to a trading platform. Automation saves manual order entry; it does not itself guarantee a good price, profit or self-custody of the bitcoin purchased.
Imagine wanting to spend the same amount of money on bitcoin each week without opening the exchange and entering an order every time. Founder Luboš Kovařík describes a similar need: he wanted to automate his own approach. Štosuj handles the orders, the exchange or broker maintains the trading account, and your own bitcoin wallet provides self-custody after withdrawal. Signing up for the app therefore does not mean that you control the bitcoin with your own keys. The terms effective from 29.7.2026 name Stosuj s.r.o., company ID 14399831, as the operator. The company describes the service as software rental rather than portfolio management or individual investment advice. Choosing the rules and bearing the trading risk remain the user's responsibility. [1] [2]
The exchange connection uses an API: an interface through which programs send requests to one another. When a condition chosen by the user is met, a webhook sends an automatic message, and another part of the system turns it into an exchange instruction. Štosuj's technical description identifies an adapter based on XChange, a library that provides a common way to communicate with different exchanges. It offers separate containers—isolated environments for running software—for individual connections in the AWS cloud. Self-hosting is described as a feature still being prepared. Requests are meant to pass through a forward proxy, an intermediary that allows access to be restricted to specified source IP addresses. This IP whitelist controls where a request can come from; it does not specify which bitcoin address may receive coins. [3] [11]
An API key is a way of granting the app access. It need not give it all the powers of your normal login. Reading a balance, trading and withdrawing funds are separate permissions. Štosuj's general FAQ says that the app cannot move funds out. However, its terms allow withdrawal permission for supported automatic BTC withdrawals, strictly with an active list of permitted destinations containing only the client's own address. The enabled feature and the actual exchange permissions therefore matter. An API key is not a wallet seed, the backup used to recover its keys. You can revoke the connection at the exchange; even trade-only access, however, cannot prevent losses caused by poorly configured orders. [1] [2]
Buying a fixed amount at regular intervals is known as DCA. Dynamic DCA adjusts that amount using selected indicators. Štosuj describes BTFD, based on the price decline from its peak; NUPL, an estimate of holders' unrealized profits and losses; and the Fear & Greed Index, a measure of market sentiment. A chosen multiplier may increase the purchase amount during a decline. That requires more available money, not merely a different moment to spend the same budget. A historical backtest simulates rules using past data. A lower average purchase price in that simulation does not tell you the future outcome, and comparisons must also account for differences in the amount invested. [4]
A grid is a series of price levels at which sales and repurchases alternate. If the price reaches a selling level and then falls to a buying level, a pair of trades can be completed. But the price may never return: some bitcoin can remain sold while the market keeps rising. Profit on completed pairs is therefore different from the performance of the whole portfolio. Fees and the value of the remaining BTC and cash also count. Štosuj's guide lists this strategy for Coinmate and describes Anycoin support as being discontinued. Its comparison baseline is a one-off series of staggered sales, not simply holding bitcoin. An exchange being supported does not mean that every strategy is available there. [5]
The price list distinguishes the FREE plan from PREMIUM at 150 and PRO at 450 Štosáky per month. Štosáky are internal credits used to pay for the service. The exchange rate, markup, and fees for the particular trade or withdrawal still matter. For example, regular DCA labelled MARKET at Coinmate uses Quick Buy/Sell, not the fee schedule for an advanced market order. For Anycoin, the fee overview lists a 0.9% markup on regular DCA MARKET orders under FREE; it also lists that markup for an immediate exit sale regardless of subscription. The same order-type label may therefore carry different costs in different features. What matters is the specific quote and the current total cost. [6] [7]
The name Cashback saty may suggest that you already hold actual bitcoin in your account. Under the terms, however, these are loyalty points that cannot be withdrawn to a bitcoin wallet. Following the change dated 27.2.2026, the guide lists rewards of 10% for PREMIUM and 20% for PRO out of the commission Štosuj receives from Coinmate and Anycoin—not the full trade value. According to the description, points can be converted into Štosáky or donated to the project. Expressing their value in satoshis, bitcoin's smallest units, does not turn them into BTC you own. Withdrawal through Lightning Network, a network for fast bitcoin payments, is described as a plan rather than an available feature. [8] [2]
The Kicom review linked by Štosuj dates from June 2022. It can help explain the idea of automation, but the app's appearance, subscriptions and features have changed since then. When setting up an account, current instructions therefore carry more weight than the location of a button in an old video. The Trezor page combines educational tutorials with a discount offer and affiliate links that may earn the referrer a commission. It helps to recognize these different roles: a wallet explanation can be useful while a purchasing recommendation also has a commercial context. [9] [10]
