There are currently three ways to steal Bitcoin. First, hackers infect crypto asset exchange servers with special malware via e-mail, websites and popads and infiltrate devices. This happened with the Binance hack last year.
Second, take apart the Bitcoin hardware wallet and get the seed phrase. This has been practiced by Kraken against Trezor.
Third, hacking into the Bitcoin blockchain network itself through “51 Percent Attack”. This third method is considered expensive, but has the potential to get the largest loot than the other two methods. This third method, according to observers, will cost up to US $ 21 million.
So many mistakes within one post...
First of all, these are not ways to hack bitcoin.
If we agree that this is what "hack" means then your title doesn't make sense:

Third, hacking into the Bitcoin blockchain network
Hacking into the bitcoin blockchain network? Neither this makes sense. It isn't a computer.
"51 Percent Attack" isn't hack. It is the pool with the most cpu power.
third method, according to observers, will cost up to US $ 21 million.
Multiply it with 100 and you are closer. Believe me if it costed **only** 21 million dollars, everyone would make a 51% attack.
