I think about this often. I have very little money in crypto as of now, but I still think about the possibilities of someone snatching it up from me. Even with my small amount, if they did so across a large scale, it would amount to be quite the profit for them.
So that being said I have definitely been thinking about investing in some more security once the time comes. When I say "once the time comes", I simply mean that by the time I can easily pay for the security with some of my crypto earnings, that's my sign it's time to start protecting them more.
Thanks for sharing :) I also have a Mac, so I will definitely keep this program in mind(although, obviously I will do my own research)
