Unfortunately, hacking cannot be prevented and it is happening in all aspects, not only toward Bitcoin and crypto. Exchanges have large amount of valuable crypto currencies, surely the hackers will be targeting the exchanges.

developers often incorrectly assume that the words "crypto" and "blockchain" mean security by default. "Due attention is paid neither to the quality of the code nor to the network architecture — and they can be vulnerable. Special attention should be paid to the security of smart contracts. And here they often rely on the security of the blockchain structure, losing sight of the unsafe use of pseudo-random number generators, using data from the main Bitcoin network or similar currencies as a source of random value

Hacking accounts from crypto wallets are very dangerous. So all those who hodl, please be mindful about whom and where we will be giving our confidential information, we also have to enable 2 factor authentication as long as it is possible for us to activate it.

Bitcoin to be exact has never been hacked. Although of course various wallets have been hacked so whatever they contain should have been taken by the hackers, that includes of course Bitcoin. Crypto hacking is widespread but that is going to be expected because there is so much wealth in there than somewhere else. The hackers must also be choosing which one is going to be worth hacking and a bit easier to escape from. That includes individual wallets. That is why extra care should be given in saving private keys and PINs.

Money is always a good target for people who want it badly. Since you don't have to forcefully or physically get into somebody else's house, so they turned into hacking using the internet which is for them the safest way of getting money from others. Which is not good and really needs to be stopped. It is not only that they are focused on cryptocurrency, almost everything for as long as it is related to money, hackers would always find ways to get into it no matter what. This is the reality and we need to be always alert on things we often do especially if involves internet connectivity.

Hackers are looking for the money. Cryptocurrencies are good target because very often they remain unprotected. As well as some exchanges. By that I mean mostly on personal wallets and online wallets who could be especialy vulnerable. People are not as careful as they should be anf often don't protect their coins. And we are all aware that people are the weekest chain always making mistakes.
Also, by hacking cryptocurrencies hackers get the money that is easier to hide traces than when you steel physical money. For hacker internet is like playground with endless possibilities to get the money and they are using every opportunity.

Some new investors or people might misunderstand your post.

You see, Bitcoin and other cryptocurrency can't be hacked. It might be in the future, I don't know if you already knew this but Bitcoin in the past was hacked but it is quickly recovered and after that it is not been hacked again. Though Gambling sites, exchanges and some online wallets can be hacked so you need to be careful where you put your cryptocurrencies.
