Mark Zuckerberg and Jack Dorsey are lending their considerable influence and expertise to blockchain and cryptocurrency, but even their efforts may not be enough to spark a global network of crypto-accepting merchants.
The problem they face is that, years after bitcoin and other cryptocurrencies came to market, there is still no tried-and-true method to enabling their use. Square's approach is to pin its hopes to the success of bitcoin, a tactic that rivals such as

Whatever path they take, both companies will face the same pushback from merchants in accepting non-government backed currency for payments in stores.
"There are literally thousands of cryptocurrencies and only a few have a meaningful following," said Richard Crone, a payments consultant, noting Square is not supporting bitcoin for retail payments but for investment via Square Cash. "Facebook and Square could get their own cryptocurrency, but for what use? You need a network for acceptance."

Marcus became head of Messenger four years ago, and since that time the app jumped dramatically in users and in its transaction capabilities. Marcus went to work quickly, adding a

Facebook Messenger's entry into the payments business was also influential enough to draw a competitive response from
Beyond Facebook, Marcus has a long history in payments technology. Marcus was president of PayPal before joining Messenger, and earlier in his career founded Zong, a mobile payments pioneer that drew more than 250 mobile carriers to its mobile-phone-based payment system. Rather than trying to compete, PayPal acquired Zong — and hired Marcus in the process — in

Given this experience, it's easy to see Marcus using the blockchain to spin a mix of content, merchant services, social tools, a buy button and a virtual currency.
Facebook would not comment on the possibility of Facebook having its own "coin."
"Like many other companies Facebook is exploring ways to leverage the power of blockchain technology. This new small team will be exploring many different applications. We don’t have anything further to share," a Facebook spokesperson said in an email.
But even given Facebook Messenger's success in adding transactional capabilities, embedding a non-fiat currency would have the same result as other attempts to build a crypto payments market—namely a group of merchants that are nervous about the volatility and lack of oversight and risk inherent in cryptocurrency.
"Facebook would rally interest in mining a Facebook cryptocurrency and people would accumulate and buy and sell it," Crone said. "They do have a brand, but payments is a multi-party market. You could send 'Facebook dollars' to pay for rent or split the dinner bill, but converting it to real value is the key here to use it for retail payments."
The bad publicity surrounding Facebook's recent privacy breach might hurt its efforts to brand itself as a platform for payments — but then again, Apple famously announced its own mobile wallet in the days following a massive leak of intimate celebrity photos from its

"What's going on with Square? They are using bitcoin trading to help build prepaid balances. Unlike Zelle, any nonbank P2P app is built on amassing a prepaid balance, then the user monetizes that when they make a purchase," Crone said.
