Yesterday the Central Bank of Albania issued a warning about the uncertain and unsafe nature of cryptocurrencies
They called on people not to get involved. Should we be afraid or the banks are!
Its central bank responsibility to issue warnings in best interest of public interest to keep them safe from financial frauds and scam type scheme. We see lots of ICO scam every now and then, so central banks are not wrong in issuing warnings against these risky investments.
On the other side, yes central banks are scared of BTC, as it will bring transparency and will decentralize the monetary control, which is not acceptable to central banks.
