i think with AI added into the mix and people paying for super computer access it's only a matter of time before we see pockets of those with the power using it against things like crypto. it's how the community deals with that, with their own white hat AI i guess! let the battle of the AI trading bots begin!
I wonder if the Bitcoin charges and slow transactions could affect this, but they may be using 'virtual trades' just to spook others into buying or selling. With free and fast transactions on the Steem blockchain it may be possible to flood the system.
