What are the disadvantages of a cryptocurrency tra

Earning millions only on advisers only seems real. Often such slogans are used by scammers who sell a dummy, which, at best, will not bring any benefit. Trading robots also have a lot of disadvantages, and let's list them.

Expert Advisors should not be used during times of market instability. Any unexpected news can drastically change the direction of the price. The robot will not even know about it, so it will make unprofitable deals. Therefore, at least you will have to look after the program.
Helper programs use only technical analysis, which is based on effects, not causes.
The program has no emotions. Yes, this is not a mistake. The lack of emotions in a trading robot is also a disadvantage. If something does not go according to plan, the person will get scared and close the deal, but the robot will not be able to. Of course, if it does not have a loss control mechanism, which most Expert Advisors do not have.
The ideal way to solve these problems is to turn the EA into semi-automatic mode. That is, the robot will only give signals, and the trader himself decides whether to listen to these tips. But then some of the benefits just disappear. In general, a competent trader knows how to deftly balance between the pros and cons of advisors.
