According to Crypto Slate, the Blockchain Transparency Institute (BTI) released the latest report saying that after several months of research, BTI found that more than 10% of the transactions in the currency were cleaning transactions. Most of the 30 trading pairs on the exchange are cleaning transactions, and some trading pairs present up to 75% of the cleaning volume. Bitcoin and Ethereum have between 85% and 95% legal transactions. Although the currency is relatively clean compared to other platforms, it is no longer considered a “validated exchange”. The report also said that about 88% to 92% of daily trading volume was fabricated on the day, while about 92% of Bitcoin's daily trading volume was forged. Of the top 40 exchanges in actual trading volume, about 65% of Bitcoin transactions are forged, and almost all counterfeit data comes from OKEx, Bibox, HitBTC and Firecoin.
