Can you advise whether it is advisable to use a trading bot to trade cryptocurrency?
Such bots are sensitive to volatility, which often happens in the cryptocurrency world.
And how will the bot behave in a falling market?
I used one well-known bot for a month and it made 25% of my balance in a month.
And now I want to invest a lot more money in it.
The bot can usually do, repeatedly, what you would do - if you've set it right.
Since you've used bots, you should know the basics.
Whether it's advised or not to use them.. it's debatable. It depends very much on how much configurable the particular bot is, it depends on your overall trading skills, it depends whether you can configure it properly.
And it depends on what the bot does - scalping, DCA, arbitrage, whatever.
So there's no best answer to this question. My advise is to read more, especially reviews from people actually working with trading bots. One such website I've got to read at some point in the past was
https://tradingbot.info/ I can't really tell whether it's the best or not, but in the results area you may find interesting things.
My advise is to think it over very good, since the fact you are asking us this may mean that you don't have yet the experience you need (and then you should wait) or you have doubts (hence you should wait). Balance everything and ignore the FOMO. Trading is about using your brain and staying cool, not about FOMO.
But I am more a HODLer type, hence I may be wrong, and, no matter what, it's you who have to take the decision.
