You can say it hasn’t been hacked, but many people who have used it have been hacked. It’s not just people who didn’t know how to secure a computer, either. The biggest exchanges have all been hacked at one point or another and lost crypto, some of the most recognizable names in crypto have been hacked. What good is a currency that isn’t safe even in the hands of experts?
