I read it somewhere in this forum only, more precisely in the discussion section. Hence I said AFAIK, not sure. But it seems you are confident that it is not banned at Messi's homeland. So r u from Argentina ?
I've searched both the forum and the news about bitcoin.. nothing:).
https://bitcointalksearch.org/topic/2014-05-30-argentina-gets-home-grown-exchange-defies-central-bank-631949The argentine central bank is said to be hostile , but there is no actual ban.
“The Central Bank is currently analyzing various scenarios to verify that transactions involving [cryptocurrencies] do not constitute a risk to those aspects which monitoring is expressly stated in its Charter. The so-called “ virtual coins " are not issued by the Central Bank or any other international monetary authorities therefore have no legal tender and have no support . Also, there are no governmental mechanisms to ensure its official value. Virtual currencies have shown great volatility so far and have experienced substantial price changes. These implications, the risks associated with transactions involving the purchase or use of virtual coins as payment, are borne by users.”

As per Bitlegal.net the legality of Bitcoin in Argentina is considered friendly although your note seems more recent so did it change?
Inflation has been a significant problem in Argentina for many years, and citizens have long held U.S. dollars as a stable currency. However, in 2011 the country began to clamp down on citizens' ability to obtain foreign currency for savings or international purchases.[1, 2] Under General Ruling 3,210, sales or purchases of foreign currency through licensed foreign exchange entities must be cleared by the Argentine tax authority, which may either validate or deny the transaction. Central Bank Communications “A” 5318 (July 5, 2012) and “A” 5330 (July 26, 2012) forbid individuals from holding foreign currency for savings purposes. Argentinians hold an estimated $160 billion in US currency. In an effort to inject this money into the Argentine economy, the government began issuing certificates, known as Cedines, in return for dollars turned in by individuals as part of a tax amnesty plan.[3] The financial regulations and fluctuations in the Argentine peso have created a vibrant environment of personal bitcoin users who view the digital currency as a safer option than anything provided by the government - this is currently manifesting as a shadow economy.[4] Although there have been no official pronouncements from Argentina’s government, use of bitcoins is a poorly kept secret, so it is fair to call the government “permissive” - for now.
