Starbucks' executive chairman and former CEO Howard Schultz said on conference call to investors, regarding the topic of cryptocurrencies:He seems to be aware the power of Starbucks and whichever coin they may choose, will do a lot to legitimize that currency, stating:However, it's unlikely to be Bitcoin, adding...Yeah, it's all very vague I know. But let's remember - Starbucks was out front and way ahead of the game when it came to mobile payments, so it wouldn't be much of a surprise if they lead the pack again when it comes to cryptocurrency payments as well.
