"Bitcoin transaction is irreversible". I would have loved it to be, but there are reasons why it's not. Also, a transaction that was made from one bank account to another is irreversible too. So it's not new.
I don't know the details but if for some reason you make a wrong wire transfer the bank should be able to get the money back. And if you receive some money that you were not supposed to receive and you decide to simply keep it/spend it then you are going to be in some serious troubles. With bitcoin none of this happens and I never know whether consider it something good or bad.
I mean there are levels to that, you are capable of doing it if you want to, like chargebacks, but it is not that easy. The ability to chargeback a charge on your credit card and trying to reverse a wire transfer is not the same, there are difficulty differences. In one case it could be done, and in another it might be an issue.
I believe that we need to make sure that it is not a wrong transfer, we need to be aware of what we are doing and we need to take care of the parts that we have. Otherwise, we are going to end up with a trouble and we should try to avoid that. If we make a wrong move in crypto, there is no way to reverse that, it's gone, but it's not that easy like a click of a button in fiat neither, so we should still be careful.
