I don't believe in trading bots, if anyone could program a good trading bot he would probably become a millionaire instead of selling his bot.
And every investor needs his own strategy in trading, copying is not a good strategy.
There are some good bots and you can read about them how they work, not everyone who can develop bots is good at trading because developing bots require coding knowledge and API implementation such that the bots are working in tandem with the exchange and placing buy and sell orders for your account, which you input into them.
Bots are now in high demand with the rise of more effective crypto exchanges, due to their aptitude for generating lucrative crypto trades each day. Facilitated with profound algorithms and handled by pre-eminent companies, a multitude of bots are found all over the market with their functions and drawbacks.
Right but I would say that if a bot is actually doing copy trading then better to stay away from it because copy trading is indeed one of the worst ways of trading as you are fully dependent on someone else and his success will only bring success for you plus their commissions I guess are involved for copying their trades.
