There are alot bots for cryptotrading and they use classical technical analysis methods, indicators, parameters. Whales are trying to convince people to rise or fall according to their plan. But when it comes to bots it is easier to convince them. Because bots are generally using known methods and indicators whales can collect stats and triggers that bots like market is rising. This will allow a lot of bot to buy with their balance and after price reached a certain point that whale sees it is profitable all assets are sold to market and eve after profit whale again sell more to fall back to its bottom target for to prepare another fake rise. Bots can be triggered for rise or fall. So we can not know when excatly this is happening but there are some clues at whales movements like angle of change and volume. Good luck with bots
Reason why people use bots is because bots unlike humans don't feel any greed or fear or emotion.
You can easily mimic your human trading into a bot that will always be up and will be super fast and won't make any user errors.
You can make alot of money on exchanges like Bitmex if you configure your bot to be an market maker where you collect the "maker" fees of 0.025%.
Issue is you need to be very good a programming, have a very good latency to the trading API server and for arbitrage need alot of BTC for capital to make it work.
