The Wall Street Journal released an investigation accusing USDT issuer Tether. It said the company used shell companies and dubious accounts to access the banking system in 2018.

Tether has already responded to such allegations. They called the Wall Street Journal's claims "completely inaccurate and misleading."

"These unfair attacks will not prevent us from continuing our efforts and offering the most liquid and trustworthy stabelcoins recognized by the market and making us a leader in the industry."
