there's huge difference between attacking 24/7 hashing power and attacking hashing power of people sending transaction so a significant player w/ 24/7 level of hash would have near zero competition on iota from casual users, so it literally does not matter. Only reason it's not attacked now is because of coordinator making it equivalent to centralized database much like onecoin.
I haven't seen anything positive about IOTA yet that's not obvious shilling. I can see it being great for useless concept of IOT , usually refered to as
internet of shitIt's not first quantum proof blockchain, it's not even double spend proof, it's not first without fees either (steem) nor is it fastest (steem/bts)
do a search of quantum resistant blockchains, there's like a 100 that claim to be first.
