the new update make you use all 3commas in binance all features free but you must move funds to Separated wallet than binance
i use 3comma for a long time but this concern me about safety
coz i dont know where is my money is binace or 3commas
3commas is new and looks professional unlike other scam crypto trading bots out there. However, you should still be cautious when it comes to services like these that control your money or trading account. They can easily say that their bot made some bad trades and lost your money.
Personally I'd wait for some more people to try it and give reviews before actually putting money into it.
