Volatility is a relative term. Some things are more volatile than others. Show me one fiat currency that has lost over 80% of its value in a year and it has not been considered a disaster for the country. Precious metals are much more volatile than currencies as governments work to limit currency volatility. That is one reason that people were not allowed to own a lot of gold when currency was based on gold. The buying and selling of gold would make currencies too volatile for a stable economy.

You can only lose your direct investment

You are correct if you only look at the Bitcoin miners. The people who bought Bitcoins then they were anywhere over the current price will lose money if they need to convert them to conventional currency. Also the buying power of Bitcoins will be less as prices in Bitcoins go up as the value of Bitcoins go down.

Here is where set theory and averages do not match. Even is the average person only knows 15,000-30,000 each person will know a different set of words. For example one person might not know the word "elucidate" but another one might not. If you union the sets of words each person knows that set will be much bigger than 15k-30k.

Comparing Telsa with Delorean is not valid.

The company failed because the high expectations and desires of the founder John DeLorean did not match the realities of the level of manufacturing technology and market demand of the late 70's and early 80's. The car was also an under performing over priced piece of junk. The only unique aspect of the car was the gull wing doors and stainless steel skin, everything else was a technological compromise that resulted in lack luster car.

Tesla actually makes decent vehicles.

Comment Re:Rail line (Score 1) 206

A major advantage of the rail route is speed. The train took just three weeks to complete a journey that takes up to six weeks by sea.

Is that compared to a huge container ship that could not pass through the Suez Canal and therefore has to go around Africa? Going around the Horn will add thousands of kilometres, and therefore time, to the trip. The China-US route is the opposite in that the rail route is 13,000km while the sea route is 7,000km.

It is also more environmentally friendly than road transport, which would produce 114 tonnes of CO2 to shift the same volume of goods, compared with the 44 tonnes produced by the train – a 62% reduction.

I find it interesting that the compare rail to truck and not ship. Ships are known to burn less fuel per ton/km.

I wonder how much it cost to pull this off. With 3 train swaps due to rail gauge differences and 16 engine swaps this would be an expensive trip. That was a publicity stunt as it only involved 30 rail cars. In the arena of Chinese trade 30 rail cars is insignificant. I doubt they could economically do this on a large scale.

Containers destined for rail cars wait at the station for the train to come in, wait while to be moved around the train station, wait till the other containers are loaded on the train and till everything is ready and then a similar dance at the other train station. Loading a container onto a train is very similar to loading onto a ship.

Regarding ships there's the time and expense wasted in loading/unloading and warehousing (sort of the equivalent of your TSA and checking luggages). It should be a lot easier to drive your container to a freight rail station and have it loaded on a train.

Ships take containers too so no warehousing is involved. Most sipt transport is now either bulk or containerized now.

Especially, the train would allow a "get this shipped under two weeks" scenario

Except that blizzards in Siberia and Alaska would close the track possibly for days. We are talking about a route through some pretty harsh territory.
