Automated trading is able to give normal profit only if the market is growing steadily, in this case, if the bots have a trading program designed for growth, then this can actually give a good profit.
Or vice versa, if the market is steadily falling in price and if the bots are set to trade during the fall, then the income can also be consistently high.
But there is a small but significant nuance - since the market is unpredictable, bots need to be constantly controlled, directing them in the right direction.
Otherwise, they will trade and create big losses for you.
