Fiat Currency is something visible and Feel it. Fiat Currency is Dollar, Euro and Rupees.
Recently in srilanka . Rupees depositing to buy Bitcoin Prohibited By central bank of srilanka.
As a Result of this we unable to deposit money but can withdraw money to srilanka.
This happened why , For Binary option some are investing 10000$ usd and more but lost it.
Binary option is a gambling. Only Foreign Exchange goes from srilanka. No Incoming of US dollars to Srilanka.
Bitcoin is nice investment , If you go back to 2009 , 1 btc was under 1 $. now it 10,000 per 1 BTC.
It was 20,000 per btc on January 2018.
If you want to get Bitcoin from srilanka. Only there are two ways
1. Buy from Localbitcoin
2.Buy from Local selling groups and persons.
Beware from fake people. Lot of people are misleading you.
