It was influenced by the price of bitcoin that falling down. Actually this condition make all of bitcoin users to be glad to do transaction with bitcoin. And i hope too the fees go down again to minimize our transaction amount. This is one of the advantage in using Bitcoin now.
Maybe it was influenced by the price, or whatever reason it would be. For me, this makes btc users happy. The main idea when transaction fees are reduced is that, it gives interest and make people opt to use bitcoin more. Investors also would come and buy since price is low plus transaction fees are low, thus giving them a good package if they invested on bitcoin.
