Crypto trading has become so much simpler especially since automation has been made easily available. If you are good at coding then you could use any of the popular APIs to make a bot by yourself to help you in carrying out simple trading activities. But for the others, there are ready to use bots like Bitcoin Loophole. These bots are backed up by powerful algorithms which can perform quick calculations and thus come up with the best trading decisions. There are trading bots that do work well and these can be useful tools for traders. But we cannot say that this domain is totally risk-free. When you are using trading bots you should also be aware of the risks involved so that you can stay away from the risky ones and only pick the most dependable ones.
Even the best software designed by the most talented teams around the world tends to have tiny glitches. These can all be captured only if there is a stringent testing system in place. But there are some bot developers that focus only on the development part and not enough on the testing part. In such cases, the bot tends to be released into the market with tiny glitches. The real problem would only occur when there are some tricky conditions in the market where the weak link in the bot gives in and the bot crashes unexpectedly. This is also because bot training requires a dataset. This dataset is nothing but historic data that is fed into the bot. Not all the bots in the market update the dataset and continue to self-train. So the dataset soon gets outdated and the bot would not be prepared for the ever-changing market. This again might cause the bot to fail.
When you trade by yourself, you would have come across the problem of overfitting which makes the strategy too sensitive. This occurs if you rely only on a very few technical indicators to form a trading strategy. Similar problems could also be faced by trading bots if there are not enough technical indicators being analyzed. The best choice would be to use trading bots that come with the feature selection ability which helps them decide the best parameters to use for making every trading decision in every market condition.
