Those issues have been known for a while so it's no surprise they haven't affected the price in the last 24 hours. Explaining Bitcoin's price movements is a bit like astrology but this guy probably lifted some spirits today: https://media.giphy.com/media/8cTtn78RkOAk8/giphy.gif

There's a lot of shady movement going on in both BTC and ETH right now. We're seeing pretty violent swings. I'm guessing this is a symptom of the uncertainty. We'll likely see a downtrend overall in the next few weeks. Daily movements are day by day.

The 24 hour upswing may be another bull trap masking the bearish trend that has taken hold for the last month, which has hit the entire crypto market and sent some market caps down over 50%. The BTC scaling crisis has been a known factor for even longer than that and may have precipitated a runup in other coins that directly preceded this downtrend.

Because the OP is FUD, not a well-founded concern. The network has already overwhelmingly decided on a scaling solution. https://coin.dance/blocks
