I think it is a cycle. Hackers beats the security systems then the security systems improve then hackers tries to beat the improved security system and so on. I think the best move here for us consumers is to take care of our access. We should always look out for phising websites and transactions over unsecured connections to eliminate human error in our part.
Correct! This is usually the trend on cyber space, where security systems need to become improved over time. Hackers will always find a way how to penetrate a specific system, but developers are always aware of this, releasing proper patches and bug fixes to address such issues. Until today, I think cryptocurrencies are safe enough if you make use of a hardware wallet. But, if the devs of a specific coin are careless and don't make sure that the network is resistant against 51% attacks, then the hacker could easily disrupt the cryptocurrency's blockchain.
Therefore, even if you were to hold your coins safely on a hardware wallet, you would be subject to the risk of a hacker successfully performing a 51% attack on a specific cryptocurrency's network, if the devs don't manage to fix it on time (like what happened with Verge). All in all, sometimes we as humans are the critical error of any system no matter how secure it is.
