Skilled exchange traders learned to use the programs facilitating trading process long ago. It can be as semi-automatic trade advisers and completely automatic bots.
These programs trace the price chart of an asset and find an optimum point for an entrance to the market. Completely automated soft does not assume intervention of the trader in process of the auction.
The strategy of bots in the crypto foreign exchange market, as a rule, comes down to the creation of "false" warrants. Warrants are formed with one purpose to provide the illusion around a digital asset. Thus, manipulate the price in the necessary direction, deceiving other investors. Fake warrants at the right time are simply canceled.
‼Bots in the market of cryptocurrencies is a serious problem. Owners of the crypto exchanges need to think seriously of maintaining own reputation and to introduce internal rules and restrictions.
But they're legal, afaik. Bots have its own pros and cons so its really so we really can't do anything about it. Although I haven't used bots of sort in my trading, others find in advantageous though. Yes, it might send false warrants so you have to be very careful as a traders. Besides, this is just bots, we humans still makes the decisions to its still up to us if we wanted to used it or not.
