RE: Warning: Some bots are not giving good vote even it says ROI: 10%, a method to learn if a bot is good or not

It's not about luck, it's about calculations and math. You should use better bots next time.
If we're talking about luck, I must be the unluckiest person alive. Because when I change my Steem to SBD, Steem/SBD price increased. And I also remember I bought around 15 SBD with high amount of money, because I bought when it was over 7 dollars.
