# 1.1 System balance top up

To successfully launch the Hash7 trading bot, it is necessary to initially top up the system balance to pay for the subscription. For correct balance top up, please use the instructions in the section [2.1 Balance top up.](../quick-start/2.1-balance-top-up)\


When replenishing the system balance, **please pay attention to the availability of funds to pay for the subscription, as well as 20% fee from the trading profit of the bot.** \
It is recommended to have **at least 20 USDT on your account balance**, because insufficient amount of USDT on your Hash7 balance will lead to trading termination. \
\
**It is important to note that the funds in your exchange balance are used solely for trading and Hash7 does not have access to them. The Hash7 system balance is required to pay for subscriptions and fees.**
