Probably everyone just thought that it's bottom for IOTA, the was affected the most by this bloodbath. but yeah, it looks strange that coin value is rising when everyone else is falling.
I don't think iota was going that much up. Look at the charts on coinmarketcap and you'll see that at the same time eos went up more that iota, while cardano and bitcoin cash were also going up, but a bit less rapidly than this coin. All these changes are so insignificant that it doesn't even make sense to discuss them. I believe in iota as a project and I hope it will manage to solve the problems it has for now with security. I have never seen a project so different from all others like iota is.
