I simply don't think that trading bots are capable of cryptocurrency manipulation. Yes, bots are been created by human/traders for trading but it's for efficient purpose. To make trading easy and faster so traders and mostly (heavy traders and those who probably) won't have to do everything manually. So I don't see how the bot 'itself' manipulates, except those using it for pump and dump purpose.
Well programmed bots are far more capable of manipulation than people themselves are, and that by orders of magnitude. In most cases it's even less obvious than when manipulation happens manually.
Most institutions use a wide variety of bots each targeting a specific aspect of the market they are working on. Bot manipulation goes way further than simply buying up the price and then dump the price down.
The average user occasionally buying and selling crypto isn't affected this manipulation at all, more so the cowboys thinking that trading is an easy way to profit, but that's what they have to accept when trading crypto.
Don't want to be subject to manipulation? Don't trade.
