As investors enter the second quarter looking for signs of growth sectors, cryptocurrencies and blockchain-related markets remain at the top of the list in potential. In particular, the advantages of blockchain technologies and their secure, immutable shared ledgers are rapidly gaining recognition in the international trade and finance, security, gaming and healthcare sectors. Several companies are advancing programs to educate the broader investing public about blockchain technology. Those companies include SinglePoint, Inc. (SING), which has been aggressively making strategic acquisitions and building a diverse portfolio in the blockchain space. Other public companies pursuing opportunities in the expanding blockchain sector include Longfin Corp. (LFIN), Accenture PLC (ACN), Marathon Patent Group, Inc. (MARA) and Overstock.com, Inc. (OSTK).
