The Petro is my favorite crypto because a government or central bank cannot control currency no matter fiat nor digital. This issue that has been proven time and time again through out history. However seeing the Petro fall is not where my favoritism lies. It is the domino effect it will cause.
I know there are multiple crypto currencies floating around the country. Some are are actually trying to save the people, DASH and Smartcash are the most known working on this. If these have infiltrated the country Im sure the top dogs like Bitcoin, Bitcoin Cash, Ethereum, and Litecoin are HODLing around.
With a currency crash or the actual current one happening now Venezuelas citizen's will have the option of using other forms of payment. I believe the Petro's fall will result in wide spread use of the crypto's mention above.
Also to put the cherry on top electricity in the country is free, thus leading to the educated to profit from mining. With the correct removal or change of government Venezuela can actually prosper through true financial freedom that crypto can bring.
This is why the Petro is my favorite crypto.
