The safest way to keep bitcoin is just secure your account in bitcoin.
Do not let anyone to know your email or private key of your crypto wallet unless the people which will you give your passward is your family or trusted people. Be aware on hackers.

I think cold storage is best way to keep bitcoin because bitcoin will not be affected by hackers.
but you must be careful when it's lost or damage, how ever you could even out an USB stick and hold your BTC there in offline mode. because hacking is not possible in this way.

I think anything related to technology or electricity can be hacked. Is it the hardware wallets work with electronics and they are using encryption at a high level but there are some chances for them to get hacked but they are super impossible. Even private keys can be spoofed but that can only impossible if you are physically and secured to it. I don't think there is ever anyway by which you can secure your wall it's the only way is if to use public key everywhere and keep your private key in another location Which is not even accessible to you.

Oh then that's good because i always thought that once you lose your hardware, you are going to lose all your bitcoins as well but if that's not the case then i think its the safest way to save your bitcoins.

always take note of the sites we open, use verification via email, google authenticator and messages,
and the important do not be too easy to believe with anything and anyone

Ledger is the safest way of protecting the bitcoin.Because everybody needs your approval during an exit. There cannot be any hacking.

Safest way to make your bitcoins safe is keep knowledge about it in your head and don't talk about it. When you online try to use only licensed software.

make your purse account as secret as possible. do not occasionally you share the key even if it's your family. do not you occasionally open your wallet in internet.agar stalls avoid hacking

If you want more safe than digital wallets or a software wallets to hold your coins, use a legit cold storage like ledgers for storing it as you will set your personal password to if before accessing. Aside you can keep it for more secure one, I also doubt on digital wallets and thinking what if tomorrow my balance would be zero ? i don't want to have the benefit of the doubt so i trusts digital wallets.
