Actually, the gas price is increasing when the volatility and liquidity are really high and I think this is all because of the huge amount of transactions going on for a particular period of time in the whole Ethereum Network. Even i have to post poned one of my transactions for today  because of this huge Gas prices and i think this will be soon decrease to a stable prices once the demand decreases to a equilibrium position and it will be mostly seen by tomorrow or within 2 days of time period.
