the Elsalvador President is just another amateur when it comes to crypto,he thinks he can just HODL the bitcoin without any plan,though in contrast to the investments of other countries its still way better but his mentality isn't something that should be praised.
Its the tax payers money not his own that he is buying bitcoins with,having said that all his predictions are nothing but a wish,he just wants to create enough hype and spread the word around ,nothing to be taken seriously.
