Cryptocurrency exchange FTX says it has raised $420 million in a new round of funding, valuing the company at $25 billion.

The Bahamas-based firm said Thursday it raised the fresh cash from a total of 69 investors including the Ontario Teachers’ Pension Plan Board, Singapore’s Temasek, BlackRock and Sequoia.

Specifically, the company said it attracted a total of $420,690,000 in its latest round, with the numbers “420” and “69″ being an obvious nod to meme culture.

The investment is a top-up to FTX’s series B financing round in July, in which it raised $900 million at an $18 billion valuation. FTX said it also scored an additional $100 million from Temasek which was not disclosed at the time.
