The viability, stability and future of what could be called "virtual currency" is still open for debate.
One of the things of concern is that Bitcoin and similar are not backed by tangible assets, IE Gold reserves etc, so could possibly disappear overnight. I am not saying it will, but it is a possibility.
A search of the internet reveals many scams associated with fraudsters getting involved with virtual currency, so care is needed.
Many of the scams are showing various degrees of sophistication and so are attracting tech savvy scammers.
