0138 GMT - Bitcoin rises in early Asian trade and remains above the $80,000 mark. The U.S. Securities and Exchange Commission has introduced a five-year exemption for platforms that facilitate trading tokenized stocks and other securities through blockchain technology. This measure has raised expectations for further integration of traditional financial markets and the infrastructure built around digital assets, says Antonio Di Giacomo of XS.com in a note. Bitcoin rises 1.0% to $81,873.76, LSEG data show.
