Re: What is the fate of Scammers if bitcoin later becomes a traceable Currency.
Many say here that Bitcoin can indeed be tracked for transactions, but it's better if there is a more sophisticated system to find people who commit fraud or take our Bitcoin secretly, for example, their data can be seen or their faces recorded with sensors that are has been prepared with a tool that has been designed. That's just my imagination. 
Actually it's possible if you're a pro computer specialist, it's easy for you to trace in the chain network (if it's not designed as decentralized) and breach the computer used for scamming and get the actual photo of that scammer. Soon, it will be more advanced since cybercrime now is very often and the internet is getting more dangerous than the usual days of browsing.
There will be a time that scammers will be easily tracked once a user reported a case of scam and can be traced quickly to locate the scammer. Technology is getting more development and one of its features in the future will be its tracking system.
