Which wallet is better, onchain or offchain?

[hl5460]

So blockchain.info wallet is onchain one? Right?
As per the D1T1 - Filippo Valsorda - Exploiting ECDSA Failures in the Bitcoin Blockchain analysis, blockchain.info wallet is not that safe?


So what is best option for web wallet? onchain or offchain?

[bitllionaire]

the better wallet is the one that is ONLY under your control
online wallet must be left with low amounts

Offline, cold storage for the majority of your funds.  There are a lot of discussions about how to best do this.

[H.W.Z]

blockchain.info offers cold wallet as well. It is more safe. At the creating address page, you can choose what type of address you require.

I honestly haven't heard of any production ready offchain wallets, so I would just eliminate those up front. It is an interesting concept, but hasn't been fully fleshed out yet.

The next question is web wallet vs local. Blockchain.info is a webwallet. The downside to these is that you have to trust that they serve you correct/safe javascript every time you open your wallet. If they get hacked, the bad guy could make their website give you a bad piece of javascript that would steal your password.

The final question is offline (cold storage) vs online. Most people abuse the term cold storage. Cold storage means that your private key NEVER touches a computer that is connected to the internet. Some wallets claim to be support cold storage, but it generates the private key on an online device and imports the private key onto on online device to spend your bitcoin. The only wallet that I have used that truly supports cold storage is Armory, but that is heavy weight and is a fairly advanced tool.

Hopefully this was helpful.

it's better using the two wallet than using one of them.

offchain is better

[Argwai96]

That really depends on your definition of "better"

If you do not value security at all then off chain transactions would certainly be a better solution for you because you would pay nothing in TX fees and the lost security is worth nothing to you.

If you do value the lost security from the lost control of your private keys, then the question is much more complicated. On Chain transactions do have additional security as you retain control over the money that you have not yet spend however you will have to pay for a TX fee which is generally very small.

The answer really depends on how much you value the ability to retain control over your private keys at all times

offchain is better

I choose offchain. More safer for me but works the same as onchain.

[chennan]

It is better to use both and combine their inherent advantages. For daily life expense, Off chain wallet offers the convenience and speed of using bitcoin. But you should only have small amount. Certainly the on chain wallet is good for saving large amount of bitcoin offering security. On chain wallet includes online or offline.

[Victoo]

I would use both onchain and offchain wallets both with small amounts.

If blockchain offers cold wallet then it must be more safe.

But you have to trust them.

[Q7]

The answer here is pretty obvious in terms of security. It has to offline, not connected to the network so that nobody can hack to attempt to steal it. When it comes to convenience, it all depends on how to allocate your fund. So it's pretty very much on what you want in the first place and which criteria you use to select your perfect wallet

[The Bad Guy]

Offline wallets for ever mate , Always under your control 

[1MCoin]

If I were you,I will choose the offline for sure.my hero bro.

Agree, its choosing between bad and worse.
Use multibit/bitcoin-qt or armory

[Corbuzier]

for trading, gambling etc. I use onchain
for invest in long time, i use offchain

[Jake Humphrey]

for trading, gambling etc. I use onchain
for invest in long time, i use offchain

Same

[cryptworld]

It is ok to use an offchain wallet to quick and low payments,but you should never trust an online web to have a big amount of bitcoins
you should keep safe large amounts of bitcoins in paper wallets and in your computer

[R2D221]

for trading, gambling etc. I use onchain
for invest in long time, i use offchain

Same

Shouldn't it be the inverse?
