A person familiar with the matter said that cryptocurrency options exchange Deribit is still in talks with Kraken about a potential acquisition, contrary to previous reports that the U.S. exchange has dropped a potential deal to acquire Deribit. Recent reports also confirmed that the crypto options platform is working with FT Partners to evaluate a takeover offer, but Deribit CEO Luuk Strijers ruled out a takeover. According to Bloomberg, the company could be valued at $4 billion to $5 billion or even higher. Another source said that US-listed exchange Coinbase (COIN) has also been experimenting with Deribit.
