Hello guys, So this is the second time I notice this. I seen someone yesterday buying token x with 20k usd then instantly sells the same amount of the token x for 20.1k usd, same second, nobody bought after him. I checked his contract and I noticed he made this so many times with so many tokens and he actually made good money with this. I know this has been talked before here, but how the hell is that possible? It is like he hacks smart contracts, which is not something that can be done!
