Apple's entry into mobile payments last week through Apple Pay won't really waver use of bitcoin, investor Cameron Winklevoss told CNBC on Thursday.
"I don't think they compete. I think Apple Pay is a closed system. You know, bitcoin is inherently open sourced, decentralized," Winklevoss said on "Squawk Alley," where he promoted his investment in Authy, a two-factor authentication app.
