Bitcoin Online Wallet Safe?

[marife01]

Those who have BTC online wallet, how secure it is?
I wonder how safe it is to have an online wallet for Bitcoin. Any instances that your online wallet was hacked?

An online wallet is never 100% safe, some are better than others
I use blockchain, but please don't keep large amounts in online wallets
Bulk of holdings should be held offline

Better store your BTC in an offline wallet. There is enough to read on this forum on how to store your BTC. Personally I do keep a small amount online (exchange) but that's because I daytrade and don't feel like sending my BTC back and forth...

Thanks. Does offline BTC wallet 100% safe?

Never put any significant amounts of coins in any online wallet. Keep multiple offline wallets with you and store the bulk of your coins in them. There are large number of options including USB sticks and paper-wallets.

Nothing is 100%.     99.999999%,  perhaps;  how many 9s depends on how strong your military grade physical security protections,  how strong your vault doors, and how effective the armed guards and security support teams you have helping to protect the  vaults  holding  the various segments of your wallet's private key.

It's as secure as the strength of your private key and how securely you generated that private key and kept it secret -- and the strength of the crypto algorithms.

A keypair generated using a flawwed random number generator, or based on a low-entropy passphrase  ("Brainwallet") may be guessable and less than 99% safe.

Online and offline wallets can only ever be as safe as you are. An online blockchain wallet is probably safer for a newb than someone who has zero protection on their computer, providing you set up all the provided security features - 2 factor auth and a second password etc.

For wallets on your computer, your computer might be hacked.

If you mean paper wallets, these are as safe as you make them safe. If you do it right, almost 100% safe

Thanks, nice that I could set up multiple online accounts since that is easy for  me.

You made your point clear. Thanks.

If you are going to use an online wallet at least make sure you have 2fa enabled on it.

As far as I know, Blockchain is fairly secure especially if you use 2FA. However I would be careful storing large amounts there - if there is a hole you won lose too much.

[dreamspark]

Read around or do a search for lost BTC and you will see that the majority who have lost BTC were using online wallets.

Like other people said above, online wallets are good to use for online purchase but It's not a good place to keep your main bitcoin funds as in a bank. There is a risk to get your funds hacked on online wallets while you can keep your funds safely offline on your own risk. If you download something, do It carefully as you can get a key logger or a virus which could steal your bitcoins also. So in conclusion offline wallet is 100% safe If you keep your computer safe from viruses.

I have so far found blockchain to be safe with 2FA
I never use the mobile app though as to my knowledge that's how most transgressions have happened

Offline wallets in cold storage is more safer than Online wallets. but for small amount you can use online wallets for their convenience.

This seems like a VERY BAD idea.

dont store your bitcoins online. just store online what you can afford to lose or you need for a little purchase.
