You say that as if it's a good thing.
It is. It shows that Bitcoin has become so robust that these events have minor effects.
People use positive events which have been happening for longer than just a few weeks (such as Japanese adoption) to justify unnecessarily dramatic rises in prices. What makes you think that people won't use those negative events to justify unnecessarily dramatic falls in prices if they happen later? You can't be sure of what the effects are yet, because you're not talking about the same people as you were last bubble (2013). People don't "mature" if they're new and different people each boom/bust cycle.
It would be healthy for the market to react to good and bad events depending on which happen at which time and how relevant they are to BTC users, but it's not doing that. It's just flying upwards regardless of anything that is actually happening.
Wrong. It was quite heavily swinging up and down, and even reached a bottom of $18xx.
At the start of the year, $1800 would have looked like a bubble.
There are some positive events (such as SegWit),
"Some" and SegWit can't be placed in the same sentence. You have no idea what you're talking about.
I strongly doubt that speculators know what they're dealing with either. SegWit is great but if adoption were rising as quickly as the price is (multiplying by about 4 since the start of the year) SegWit blocks would already be full, even if most people were using it. LN could take some of that strain later, but even then the price
is hyped up.
They're watching the price rise and then desperately trying to justify it with positive events even though it went up by >$1000 in a week.
Absolute numbers are useless, use percentages.
About 30%. But my view is that when you're building on a price that was high to start with, absolute numbers are nice to use alongside percentages and show just how much money you're talking about.
