Bitcoin will be very safe, and will not be stolen by others, as long as we are able to keep the secrecy of our bitcoin wallet password, and keep it well in order not to be lost or stolen by others. I think the best bitcoin storage is through blockchain, because when we will do the transaction required verification of gmail we register in the blockchain.
The best way for storing bitcoin is to have an offline wallet because it is safe from the hackers since the hackers are just virtual and they cannot be able to penetrate or hack and get your bitcoin when you store them on an offline wallet. You can get offline wallet by creating a paper wallet or buying a hardware wallet.
hardwallet is the safest option to keep our assets, everything connected to the internet has gaps that can be penetrated, in this case blockchain can be penetrated through email and so on, but the most important is our attitude and how to continue to behave in discipline in using the largest internet security is our own behavior to always be wary of phishing malware.
