I'm using BitUniverse's Grid Trading Bot, and I think it's really good to buy low and sell high everyday for me, cause the market is fluctuating recently. More importantly, it's totally free and supports 20+ exchanges like Binance. Any more bots are you using? Please recommend.

I would recommend if you are really cautious about your money, then it’s better don’t use any bots.
Normally I myself don’t like any kind of interference from 3rd party apps when it comes to money things.
Yes if you are really busy and cannot quickly buy or sell, then i would recommend using legit bots.
Personally I haven’t used any bots, but as many veteran traders have already given you so many options, then go for the desired one.
But as always i will say, stay away from 3rd parties when it comes to money.
