There's no such thing as a free lunch. You'll make peanuts from bots compared to actually learning how to trade
"You will make peanuts" if you invest peanuts it all depends on your capital. Bots are better than human, especially in trading they never get emotionally attached to altcoins, get nervous, or get panicked. You give it input, and should expect a result you mess up, you blame yourself not the bot. And GUNBOT seems to be the most popular one, as far as I've seen.
Don't really believe in bots. How can we trust someone with little and limited thinking capacity. Buy/sell algorithm that too with access of all your capital. Bots always try to cover loss and to do this they input double money of your last trade to cover loss plus gain the profit from that trade. It is really dangerous. They are not emotional is disadvantage I guess.
