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.
