Criminal minded people has been there always as they will try and hide under the umbrella of Bitcoin to scam people so the most important thing is that investors in Bitcoin should be careful do that they don't fall victims to such people because alot of person's are leveraging on the opportunities that are abound in Bitcoin
This would always be a problem for newbies as bitcoin reaching new highs would bring about interest in the bitcoin system and new investors would be brought into the system and without the knowledge, they can fall prey to scams.
I think this is a topic worth discussing and a guideline can be provided to fish these scams hiding under the umbrella of bitcoin.
