You really have freedom to choose if you will choose their trading bot or not.
You can read a lot of reviews or feedback towards their platform so that you will not be disappointed about your experience using it. Probably, you're saying that their bot is garbage because you didn't use it effectively as you use it. However, if you're a good trader and a wise investor, you will never settle the fate of your assets in using trading bot. You should know how trading really works manually, you should know how to read the market and not relying on the trading bots.
That why they end up getting disappointed by the bot results.
I'm sure that this is his mindset towards using trading bot. He needs to understand that there's no easy money in dealing with the market.
