1. One relatively major currency had dropped more than 50% in a few months (rub), resulting in "evaporation" in ~$1 tril in GDP.
2. Another major currency changed hands 20% higher as a result of one (albeit major) announcement. I am talking about CHF/EUR of course.
major brokers STOPPED trading the pair (maybe temporarily).

What does it tell you? To me it tells that a significant % of value of the above is determined by speculation and is NOT an intrinsic property.
I fail to see how bitcoin is any different. At least we know the emission rate until 2140.
I agree entirely. That explains why a move from 12 to 266 to 60 to 1200 to 160 is possible. Its mostly speculation. There does however seem to be a small component of underlying value based on utility.
The thing with exchange rates is you are pricing one money in a another money, which is as you say a largely speculative exercise.
Goods are priced in money, and so the converse is true. Money can be priced in goods.
If you do this for dollars thats how you understand the underlying value of the dollar - what you can 'get' with it. not how many rules, or swiss francs or BTC someone will give you for it, thats just arbitrage and speculation.
So it goes that you can do this for bitcoin. BTC can be priced in goods. At the moment a lot of people that accept BTC convert straight back to the dollar. The next step is that people start to transact in bitcoin using the dollar as a proxy. The more places that do this, and the more people use it, the more people will start to realise they don't have to convert back to the dollar - after all doing so is costing them exchange fees. So they start keeping a small BTC float. Then maybe people start to work entirely in BTC only converting when they have to buy something from someone who doesn't yet accept BTC, and raising there eyebrows at the same time! Then BTC is money.
The world won't change overnight, BTC going to $XXX isn't the 'success', all the people focused on price miss the point. Thats the point. Now, all of that stuff might not happen, but equally likely it could. For that reason I hold, not because my BTC will be worth $XXX in future but because I'll be able to use those BTC as money.
Because I don't know for sure though, it would be foolish of me to put everything I have into BTC and wait. So I don't I allocate assets according to risk I perceive. If I become over invested in dollar terms then maybe I rebalance. If I can afford to buy when prices are low, I rebalance.
