Bullish!  From Wikipedia, the free online encyclopædia:

"With the advent of the internet and the ability to create web sites easily without any regulatory involvement, as well as the ability to operate from other jurisdictions, pyramid schemes have continued to operate into the 21st century. It is easy for scammers to set up a web site in one country, operate from another country and target victims in a third country, hiding their identity and making it difficult to trace them. Financial regulation varies significantly from country to country, and some countries deliberately promote low regulatory environments in order to attract financial business. This makes it easy for bitcoin criminals to use this to their advantage. Financial Regulatory Authorities in each country have significant difficulty enforcing rules on scammers in other countries. With low financial literacy by investors or victims (particularly in the increasingly complex ways that global financial markets operate), and without better coordination between financial regulators in different countries, bitcoin enthusiasts continue to operate." --http://en.wikipedia.org/wiki/Bitcoin
