I think there is nothing we can do if we got scammed for that purpose here some hero members are providing escrow services better we use it to not be scammed again.
Yes, there is something you can do. I don't understand why people think the irreversibility of Bitcoin is a plus. The thing you can do is start making purchases using a credit card or debit card or payment service like Amazon Payments. All of those have fraud protection.
Reading about what Satoshi had in mind for bitcoin would support that. He says that a lot of transactions dont need the trust of a standard payment system like credit cards and we could use something different for that. So if you realy trust the one you are sending your money to you could use bitcoin. Or if the price of something is so low that you dont care you just use bitcoin.
Exactly, Bitcoin has a multitude of uses but sending $1,500 to a total stranger or unknown business isn't one of them. I hope, in time, several businesses spring up that will allow you to send insured/fraud protected Bitcoin transactions as easily as checking a box on your wallet app. Escrow is too clumsy and slow to be truly useful. Besides, escrow is no true guarantee because the escrow person might have a problem of some sort (like dying) while your transaction is in process. For now there are a lot of other options to fill in the gap.
