As Cointelegraph reported at the beginning of December, Florida-based United American Corp. (UnitedCorp) has purportedly filed a lawsuit against Bitmain, Bitcoin.com, Roger Ver, and Kraken.

The suit filed alleges that the defendants jointly used unfair methods and practices to manipulate the Bitcoin Cash (BCH) network for their benefit and detriment of UnitedCorp and other BCH stakeholders.

Also in December, Japanese police reported that there has been a significant uptick in reports from cryptocurrency exchanges about suspicious transactions. The increase reports occured after a bill came into force obliging the exchange to report such activity.
