The banking system will not fully recognize such a complex investment in Bitcoin.  Because Bitcoin works against the entire banking system.  Moreover, another issue is that banks cannot control the complex problem of high price declines in Bitcoin.  Moreover, the banking authorities cannot blame the government entirely if there is a major price fall in the banking sector.  Moreover, if the government and banking system could control the complete control system of bitcoin, then the bank and government would take responsibility for bitcoin.  Banks and governments don't want to accept Bitcoin easily because the whole system of Bitcoin is not controlled by governments and banks.  We already know about the Salvadoran government's investment in bitcoins and their falling price.  No country's government would want to invest so much in Bitcoin with so much risk.
