Bitcoin to the Rescue
When fiat currency is failing, the citizenry need a mechanism to trade and move money out of the country without fees and taxes; Bitcoin is an obvious choice.  As a “peer to peer” unit of value,  Bitcoin has minimal fees and a global reach.  It is an ideal mechanism to prop up people when their monetary system is in a shambles, and the value of the local fiat currency drops.
In Venezuela, Zimbabwe, China, and other countries, Bitcoin is the method of choice for doing business without government oversight, transfer fees, and excessive taxation.  Even in countries with stable currency, Bitcoin is a welcome addition to the mix of fiat currency, gold, and silver, for acquiring wealth and conducting business transactions.
Here’s hoping your value is strong!
