I was using localbitcoins to sell some coins. I got the money in my bank account and released the coins to the buyer.
Several days later my bank got request for wire reversal....
So, in which cases is that possible and what one can try to do to prevent it in future.
Does it work from all countries and all wire systems? (SWIFT, SEPA...) ?
The only way to fight this is not keeping ballance in your Bank, I mean cash out immediatelly
Interesting, but... cashing out wouldn't give you a negative balance in you bank account?
Indeed, that doesn't work.
Oh, it will work. It will work so well that you'll never have to worry about a bank account again.

You'll be paying it back and then some.
That was more or less my point. You can do this, but you'll have a bunch of bank fees plus the reversed transaction to pay back. You'll likely not be able to open another account at any US bank (except maybe super small banks) till you get your name clear from the several intra-bank fraud checking systems.
Paypal is similar, but with your credit. You can't just walk away from a negative account balance...
So that's why we say Go, BTC, go!
