According to Economic Confidential blog " IMF says, Crypto Assets May Displace Local Currencies in Developing Countries". Source: Economic Confidential, Facebook page..

Bitcoin is taking over the internet for online transaction, therefore, most of  the local currencies in the developing Nations are affected.. because developing Nations are not inclined in the e-currency transaction while the new generation youths use the e-currency for transactions. That making the local currency weak.

Can Bitcoin really weaken the Local Currencies in the Developing Nations?
