A crypto expert from the United States has been imprisoned 

A former US researcher for a cryptocurrency firm was sentenced to more than five years in jail

Virgil Griffith has already admitted to plotting to break US law.

He formerly worked at the Ethereum Foundation, a non-profit dedicated to the technology that underpins the ether cryptocurrency.

In addition, he was fined $100,000 (£768,000). The 39-year-old faced a possible term of 20 years in prison and a $1 million fine if convicted.

While the sentencing was disheartening, his lawyer stated in a statement that the judge "acknowledged Virgil's willingness.

"Justice has been served," stated US Attorney Damian Williams in a statement.
