Why is bitcoin and cryptocurrency ALWAYS getting hacked??

[Claus]

Is it that hard to prevent hackers from hacking exchanges, wallets and God knows what other methods they use...
I mean how on earth is crypto supposed to flourish if it's so vulnerable to hackers? Every month there is a hack that happens and destroys the crypto image yet again.

At this rate, bitcoin will go to $1 as it gets hacked every day.  Is it possible to take simple precautions to protect against hackers? For a so-called "unhackable" wallet,private key etc, it seems to be a cakewalk for any hacker.
Sorry for the rant, it's just irritating to see crypto slowly dying because of hacks.
