Bitcoin is volatile, and can easily rise and crash without good/bad news. We can think of reasons and speculate on why prices move such directions, but there's really no way to know for sure.
As a Legendary member that has been here since 2014, you should probably know this by now.
Not to mention that simply buying things with bitcoin is usually cheaper than buying them with USD, and plenty of bitcoin-accepted sites had amazing deals.
I personally bought a hardware wallet at a huge discount. And paid in BTC.
Very happy with the purchase.
