Can we use the same wallet.dat file on 2 different laptops simultaneously

Hey,

Can we use the same Wallet.dat on 2 different laptops at the same time?

Thanks

You should be very careful about taking advice from users that are participating in a paid signature ad campaign.  They generally know very little about bitcoin, and need to maintain a high quantity of posts to generate their desired income.  As such, they will typically make up complete nonsense and give horrible advice just to get a post into a thread.

This is one of those situations.  The three users (all three participating in paid signature ad campaigns) that have all responded to you in this thread so far have answered incorrectly.

While it is technically possible to use the same wallet.dat file on 2 different laptops simultaneously, there are a few rather significant risks that could result in confusion (at best) and permanent loss of your bitcoins (at worst) if you don't know what you are doing.

Haha.
Thank you for your reply.
Will keep that in mind. 

Will create another wallet, so as to avoid any problems.

I've removed all the posts that contained bad advice, as it will risk your wallet, and that's not something I can agree with. If you want to complain, feel free to do so in Meta. Thank you DannyHamilton for keeping a watchful eye.

If you want to use the same wallet over different systems use a HD wallet like Electrum or Multibit. They can mitigate some(!!!) of the risks Danny is talking about. I would say - even with an HD wallet - its not a good idea for different people to use the same wallet on different systems as there is always the chance that both create a transaction that spends the same coins at the same time or very short after eachother. If you are however using the wallet alone I see no issue when its available on different machines, besides maybe that its more likely to get compromised.

you can use the same wallet.dat on 2 laptops but this can cause many troubles so it's recommended not doing so. if the 2 laptops are not synced together due to nodes or internet problem, you may mistake the balance and transaction between 2 and create a-never-confirmed transaction also known as attacks. Anyway 2 laptops 1 address, you can lost your bitcoin if one of them are not carefully protected
