Nowadays, when there are so many hackers, the programmers will take measures to protect the system, preventing hackers from invading the user account. But users need to protect their personal and account information. Do not download any software that you find unsafe and do not click on links with strange domain names, maybe hackers use these tricks to take away your IP network.
I think when bitcoin is located on the Blockchain they are in safe hands. It is the task of bitcoin holders to protect their own coins. For the security of our valuable bitcoin, always use a bitcoin-certified cellular wallet. Let your mobile or computer antivirus and firmware be protected. Don't save your private key on it. Don't click on unknown emails or unknown links.
Bitcoin is a digital currency. It can be traded and stored digitally. Bitcoin is a high-value cryptocurrency, because it has a greater risk of hacking. Bitcoin has its own security system "Blockchain". All bitcoin transactions are verified and guaranteed by the people themselves, miners.
