If could be that the mentioned articles have something to do with the increase of price of bitcoin, although that news came about like 2 days ago already. I think the real reason is the upcoming segwit2x implementation. All investors are very bullish about this activity that's why they continued to buy bitcoin as a very steep price because the price could go higher after the segwit2x. Remember that our market is based on speculation, so the more positive news we have the higher the prices is going to be.
Just to continue to hodl and don't let your coins right now because the price is going to the moon. We should all maximized our profits. The future really look bright for bitcoin market.
