Cryptocurrency mining giant Bitmain is attempting to go public again after failing to in March, Bloomberg reports.

The Beijing-based company designs integrated circuit chips for bitcoin mining. It is working with advisors to prepare for a listing in the United States. The IPO could take place as soon as the second half of 2019. Bitmain aims to file documents with the US market regulator as soon as next week, according to people with knowledge of the matter cited by Bloomberg.

Bitmain lapsed its Hong Kong IPO application in March. After that happened, in an internal letter sent to its employees, the company said it would “restart IPO efforts at an appropriate time.”
