The boom in cryptocurrencies is creating enormous opportunities for tech and finance companies. Wedbush Securities shares 5 stocks of companies that are "attracting this new market opportunity." It also highlights an altcoin that could double its valuation over the next 12 to 18 months. Back in 2013, Wedbush Securities was the first Wall Street brokerage to issue a research report about bitcoin and its underlying blockchain technology. The company said the digital token could rise to as much as $98,500 from around $1,200 back then and described it as "a potentially game-changing disruption" to the payments companies under its coverage. In 2014, it also became the first US financial institution to accept payments in bitcoin.
