Bitcoin bull Michael Saylor has downplayed concerns over quantum computing’s impact on Bitcoin, calling it a marketing ploy to pump quantum-branded tokens. 

“It’s mainly marketing from people that want to sell you the next quantum yo-yo token,” Strategy’s executive chairman said in a June 6 interview on CNBC’s “Squawk Box.”

Quantum computing’s potential impact on Bitcoin has been labeled as a significant threat to Bitcoin’s security.

According to the quantum computing research firm Project Eleven, 10 million Bitcoin addresses have exposed public keys and more than 6 million Bitcoin could be at risk if the machines become powerful enough to crack Bitcoin elliptic curve cryptography (ECC) keys.
