There is a RevenueBot account balance to write off the service commission. The account balance is calculated in BTC. The commission is written off from the account of RevenueBot every time the bot completes the cycle of work and receives the income (take-profit order is executed on the exchange). If the income is not received in BTC, it is converted to BTC at the rate at which the income is received. Replenishments not in BTC are also converted to BTC at the rate of replenishment. Besides, the account balance is needed for making purchases in the marketplace. Referral charges are also credited to the account balance and are spent on paying the service commission, if they are not withdrawn.
