Patience is the key here! Like many other millions of bitcoin investors, El-Salvador treasury is also feeling the heat of falling bitcoin price and high volatility. Bitcoin has potential but you need to give time. It can't happen overnight.
People and especially from opposition parties will always try to find loopholes in the current system and yell about that. Just imagine, if bitcoin went upto 100,000 level, then we wouldn't have seen such statements today. So it's a matter of time and that's it!
