Maybe it depends on how we use the trading bot, because the trading bot doesn't run automatically on its own. Must be set first
and must be updated regularly to be able to get profit. For me trading bots can't make a good profit, maybe because I can't do
the settings properly. So I often experience losses when using trading bots, even my capital runs out. That's why I prefer manual
trading only.
I would recommend the ZenBot trading bot. It's an open source platform that supports a wide range of exchanges including Bitfinex, Bitstamp, Poloniex and Kraken. But there is always a risk of losing your money. This must always be remembered.
