Which got me to think about the possible consequences if El Salvador were to ever announce that it is selling its bitcoins and plans to never buy any more? I am aware that the possibility of that is low since El Salvador has always expressed interest towards bitcoin but just hypothetically, how much would bitcoin be affected if El Salvador does not show support any more?
There is no need to worry and a worry should not be overly exaggerated.
El Salvador is a country that has adopted Bitcoin as a means of payment and they have a lot of Bitcoin assets. You can imagine that outside of El Salvador or in other countries around the world there are still people who still need Bitcoin. If El Salvador were to sell Bitcoin, there would be many people ready to buy it and Bitcoin transactions would continue to run and would never be interrupted.
