I wish it was so easy that I could just turn on a bot and make all the money. We can all dream right? For me I think the better strategy is probably just buy and hold. Other wise I am just chasing losses.
Most of those bots fails, if you really want to be a professional trader then you should just learn to do your analysis yourself, if trading bots are reay then I believe by now everybody will be using bot to trade because they will never lose money which I believe that's what everyone wants, most of those trading bots are fake which you will just end up losing money, so it's just better you take your time and learn about crypto trading before you invest your money and also invest the amount you can afford to lose. Also you can just buy your coin and hold just the way @melody82 said.
A brother-in-law called me and came to my house to ask me if it is true what a robot can do in trading, (crypto trading) he told me that the investment to obtain the bot is 170usd and that you can join BInance, and that the robot makes 3 to 5 trades a day, and that it can be earned as long as you have money in the account, but that one manages, let's say, the amount of money to risk, then according to him and a friend he has it and it is something that impressed me , he made me talk to his friend on the phone, but the friend really doesn't know much, so he didn't help me at all, so I came to the conclusion that he better invest his time in reading trading books so that he himself makes his trading decisions and who will apply everything he knows about trading, is much better than a robot.
I personally won't trust a person who is giving advise that don't really have much idea on what he is talking about. I think his friend is just aiming for a referral bonus on that bot he bought. There are different kind of bot but most of them requires some trading knowledge and even fundamentals about cryptocurrency to make it more effect, Investing time on knowledge first would be the right way. Sooner or later your brother-in-law would realize that he don't need a bot just to earn in crypto.
