#Turkey has witnessed a rise in interest in bitcoin and the hundreds of other cryptocurrencies that have been modeled on it. Bitcoin trade here has gone from about 9,000 transactions a month in May 2017 to 42,000 in December 2017. A handful of companies in construction, education and the food industry have begun accepting cryptocurrencies for payment. The value of bitcoin and other cryptocurrencies fluctuates widely, leading some to caution against investment. Diyanet, Turkey’s religious affairs directorate, said in December that bitcoin and Ethereum had no intrinsic value like gold, nor were they backed by a government, so they did not meet the standards of reliability to make them a currency. Another ruling in January said the factors driving the value of cryptocurrencies were too shrouded in secrecy, exposing investors to fraud and use by criminal networks. According to Onur Baran Caglar, a FinTech consultant and lecturer at Istanbul Aydin University, the debate over bitcoin misses the real potential of the underlying technology. That real potential is the blockchain, a digital ledger that keeps track of all bitcoin transactions worldwide.
