Based on the usage by the user the safest way of having bitcoin into wallets differ. In my personal opinion most of the time I use bitcoin for gambling. For this ready access is a must and based on the same I prefer online wallets and for long term holding hardware wallet is preferred.

Online web wallet like blockchain.info is really good though for stored your bitcoins online. They are veteran on cryptocoin and maybe the best bitcoin web wallet. It's also safe but keep in your mind that don't download and open something suspicious, it might contain a virus that can hack your wallet.

Those selections are good and its the best way on storing in your Bitcoin specially you do decide to keep it for long term. Hardware wallet like Trezor would be the best choice for me since you can able to keep it physically or in your hands just store up the informations that needed to access that wallet and youre good to go. But thinking off there are still risk on lossing your bitcoin no matter what kind of wallet would you use but on this hardware wallets would somehow do have a good security on your coins.

Hi.  Interesting comments.  Pls provide evidence or a link to any weaknesses in trezor.  ?
Thanks.  Kr

There are a lot of ways on how to keep your bitcoin safe knowing that it's not physical money but a cryptocurrency. Having your very own bitcoin wallet is a good way to keep your bitcoin secured. You will have a key here which is your obligation to keep as a secret having no one know it. Make a password also that is strong enough not to be known by anyone. This is one of the best way but if you want a safer one, try trezor and cryptosteel. It makes you invulnerable from hackers.

A team of developers working at trezor have been trying to find a weakness in trezor for the past 3 years the only time anyone got close was when a developer that now works for trezor managed to find a part of the seed using an electron microscope , this issue was quickly secured with a firmware update , even then any potential thief would have had to actually have your trezor.  It is impossible to ( hack ) a trezor because it is never actually connected to the internet and your private keys never leave the device.  To date no one has ever lost any bitcoin or had them stolen while using a trezor.

Safest way is to use an offline wallet. As long as you have the seed of the wallet and you secure it, you have nothing to worry about. Trezor is not the way to go especially if you're just a newbie. It's expensive and you have to buy it from abroad.

Online wallets are completely unsafe because they can run away any time they like, plus, it's on the Internet, therefore, it can be targeted by elite hackers.

The safest way is to get a local wallet and secure your private keys, I think that is the most safest way.

Bitcoin wallets are not very easy to hack so you don't need to worry about all of your bitcoins because it is safe in your wallets. If you really need a safe wallet why don't you try to use an online wallet like blockchain, it is very safe to use and very easy. You just need to worry about is you need to remember all of your passwords in your wallets account because if you forgot all of your bitcoins will be useless.
