I doubt it, News of El salvador Is positive news it would not make sense for the price to drop due to El salvador
It would be ironic which is quite normal in markets. Buy the rumor sell the news, the reasoning being the gains before the event resemble positive action and often not just this time but predictably the arrival of a positive event can lead to a sell. But in any case I dont factor 1 country as being large enough to have that much influence on Bitcoin, this particular news was perhaps seen as start of a trend or validation in Bitcoin acceptance but that still doesn't mean that unique price and time point is upwards only.
That's right! With that news, amateur traders think that it will carry the price to rise up, but experienced traders have other things in mind. Buy the rumor sell the news often happened when you are dealing with trading.
You need to focus with long-term effects and not just for the short one, you'll be panic if you do since whales are better in shaking the market, always take your time, balancing the situation, don't rush things out as decision making should always be accompanied by good research and not just by the trending market situation.
