Are you serious? Binance and Luno have been hacked in the past? That's a red flag to all users. I'm just currently known to the use Binance having spent some time on Luno and Roqqu. This is hugeOf course it can be hacked and it has actually been hacked a lot of times. Big crypto trading websites like Binance and Luno has been hacked a few times what more an individual's wallet. The only thing is that, the hacker might not find any incentive to hack your wallet. It's only those with huge crypto portfolio that are usually targeted so in most cases the common man is safe.
