once I used a trading bot for trading on another digital exchange to check its efficiency . was given a limited amount of free trial bot funds . I selected a bot and it started trading on BTC . I was now an observer . as the funds were provided by the exchange they might have given it the instructions to be careful .... don't invest all of the money at once etc .... so for 10 or 12 hours bot just saw the chart and did nothing . afterwards it bought some bips for half of the available funds which it sold later on on meager profit . it lost some of that profit in the second purchase and sell of BTC bips . then it regained some cents in the third and fourth tradings but again lost some cents in the fifth trading . thereafter the trail period ended . the exchange took away its money and I was given the profit of those five bot tradings which it had done in 6 days . the overall profit were some cents. the experience taught me that bots can't do wonders . their intelligence is not that much of value in a volatile market .
