What is the safest wallet for Bitcoin in the UK?

Depending on the level of security you want you may use different storage devices, such as:

  • Desktop
  • Mobile
  • Hardware

The desktop and mobile version has a faster transaction speed and it’s easier to access your bitcoins.

The hardware unit is kept offline and is the best for security reasons but transactions take a lot longer since you have to start it, plug it into your pc, and then start a transaction.

The price differs a lot between all storage devices whereas the cheapest is the desktop and mobile, while the hardware is more expensive.

So, which one should you use for bitcoin?

The choice is yours.

If you are not bothered by longer transaction times and want more security for the money, go with the hardware option.

keepkey wallet

ProsCons

KeepKey storage type

KeepKey is a combination of an offline cold storage device and also a hot wallet.

The security on a KeepKey is very high since the wallet is storing your coins out of reach from internet intruders.

What makes KeepKey interesting to me is that it’s not using an operating system to handle the transactions.

This means that there is no way for viruses and malware to even latch on to the device in the first place.

Also, even if your KeepKey gets stolen or broken, you will have your 12 secret words generated to recover all your funds.

This is the reason why KeepKey is on the list for the best bitcoin wallet in the UK.

KeepKey fees

When use the Shapeshift platform to trade your digital assets with KeepKey there is a 0% commission.

This goes for all the available coins on the device including BTC.

These are some of the lowest fees on the market.
