It depends on many different aspects. Using bots is really effective if you know how to use it and find out a strong bot. There are many stupid bots which can cause you to lose a huge amount of money.
I don't really trust those bots for a long-term trading, in short-term trading, it is somehow useful but I don't see myself relying on that platform. It doesn't matter if it is a strong bot, high quality trading bot or something, I just want to learn manual trading with myself only, and improve in every transaction that I make.
The only thing in trading bot is that, there are some features that are automated compared to manual trading.
Trading in traditional ways is not always bad. If you can control your emotions and understand your money management, you will definitely be rewarded.
In trading manually, you will have full control with your assets and strategies. You can also do technical analysis with yourself based on the market and that's more precise and effective. You are your own enemy, that's why you should know how to manage yourself.
Bot is good especially if you want to keep emotions away from your trading but it lose money more than a conventional ways of trading. I learned trading in the conventional way and since then I have not really lose money compare to when I was using bot.
Most of the people here are saying that using bot can make your trading worse, which is true based on other people's experience that I heard.
