btc bots are sold to suckers that want to believe they work.
Most of the bitcoin trading bots are working and they give decent profit but it is not that worth to buy because the bots are just for the traders that don't know how to trade so they are using bots just to generate profit which is against to the real essence of being a trader. If you want to generate money from trading then you need a lot of hard work and patience and not a bot.
I find too hard to accept the point of bots are indented only for the traders who are unable to make profits from trading. Because I do see some professional traders also using bots as it is very much useful for them to save time in terms of executing trades as well as for preparing trading calls.
But I agree using bots must be against the spirit of trading and finding the joy of researches and analysis but people do give priority for saving their time rather than enjoying the spirit of trading.
