Until recently, cryptocurrencies were relatively mysterious to the general public of consumers, merchants and retailers who were unaware of the advantages that blockchain technologies could have in easing and securing private transactions. But free markets abhor vacuums, and several public companies are advancing programs to educate and bring the broader public into cryptocurrency transactions. SinglePoint, Inc. (SING) is aggressively making strategic acquisitions in the blockchain and cryptocurrency space, while an increasing number of recognizable industry behemoths like Overstock.com, Inc. (OSTK), Microsoft, Inc. (MSFT) and Tesla, Inc. (TSLA) are delving into cryptocurrencies and blockchain. Others like Starbucks Corp. (SBUX) have expressed optimism in its potential for consumer transactions, though stopping short of accepting bitcoin as payment.
