The increasing value of bitcoin has made exchanges prime targets for hacking and thus has made hacks there quite lucrative.
Before starting a thread you should really improve your English. Your post is just a statement and you poll is a total mess as even a 6 yo would be ashamed of it.
Bitcoin can't be hacked.
Wallets can be hacked.
Transactions in the blockchain or the blockchain itself can't be hacked.
I really suggest you start learning on how bitcoin works before anything else.Start in this section:
https://bitcointalk.org/index.php?board=39.0The third party services is definitely the weak point for Bitcoin. As far as I know the Bitcoin protocol has never been hacked.
Look back at all the hacks that has been done in Bitcoin and you will see that most of them were done on exchange
platforms. Bitcoin software is decentralized, but these third party software is centralized.

Just like everything else, the flaw is the human behind it.
Poll you have is just worthless.
Bitcoin network is immune to hacking but not the bitcoin exchanges or web wallets.
Neither is your own wallet on your computer if you choose to open stupid attachments or phishing links.
I'm almost willing to bet that less than 10% use a password on their client.
