In the near future can we prosecute scammers online?
If you're thinking of putting the scammers into jail, then the jail will be filled with scammers. Scammers are very cautious of what they are doing. Just like a regular criminal, they are very smart. That's why they use a dummy account + VPN whenever they are going to scam somebody. Leaving no trace about his personal info at all. And even if they give you a personal info, it's likely that it's a fake one or they are using somebody else's identity.
Is there anybody within the digital age doing some ways in how to backcharge a scammer like account bonds btc is required so it will be easy to recover theft btc?
Nope, BTC isn't reversible. If it is reversible, then it'd be just like Paypal which is used by scammers to scam people. After the deal, they will just revert the payment and claim to Paypal that their account was hacked.
If this happens, the irreversible privilege of bitcoins will vanish. This is bad for people like me that use bitcoin to buy or sell things online. I use bitcoin so that I know that once the payment is made, there's no reverting that can happen.
