Be extremely careful if:
- They tell you to upload your exchange keys to their online bot.
It's an outright scam if:
- They ask you to transfer funds.
- They tell you their bots are profitable without an audited track record.
- They tell you it's easy and that you can make money while you sleep.
- They tell you that you don't really need to know anything about trading, coding or even crypto!
All of you mentioned are indeed facts. But honestly, even some scam bots can also be successful without doing those. How? They could just simply let you run their bot for free while could silently take your info on the background -- which can be way worse than getting your funds and/or be used/sold for certain reasons. Also, there are bots that can be scam in disguise - by simply letting you use it with trial mode then have successful trades then takes requires you to pay big right after and be unfunctional.
Therefore, it is really risky to engage with bots regardless of it being new or even with a little "online" reviews and positive reputation. It can still be hard to assure how can one bot be really helpful and functional without silently taking any funds nor information from you. Manual trading is still the best option, as you can have diversity of plans that could depend on both technical analysis and current situations.
