As a trader, we should rely on our strategies because the market is volatile and bots are incapable of making informed decisions.
Copy trading can be helpful and risky. Since you rely on an individual for your trades, there are both risks and profits. It is important to run a background check on a master trader and do not copy from a single trader.
Copy-trading is risky if you don't know anything about the trader you decide to follow, so checking him out, his background, his stats (if it is available) before spending money is advisable! And if possible, before going for a copy-trade check other traders and their suggestions! Most of the traders I followed were going for more followers, they didn't have very successful rates, at least for the time I followed them.
I also tried some trading bots, but I wasn't satisfied with them! I guess it was me, I didn't want to risk a lot of money, and the strategies I found needed a bigger bankroll! So before going for a bot, check the possible strategies and how much money you need to run them... if you don't have enough I guess that will not work well!
