Will do. Just after my broker executes all my sell stop orders at -19%.

"If the blockchain is the final arbiter of ownership, is this really theft. "

That "if" is covering up the antecedent question you should be asking: is a blockchain a final arbiter of ownership? Blockchains provide decentralized ledgers. They say nothing about what happened before the entry is made.

Access is not a synonym of authorization.

"Why does Wikipedia care so much about notability?"

Lack of notability leads to lack of observation. Wikipedia depends on a premise similar to open source software: that given enough eyeballs, all citation errors are shallow. If an article for a notable person is altered, it won't be long before someone spots something odd, goes through to the cited source to see that the change is not supported by the source, and then reverts the change. If that happens on an article with low notability, it provides a means for citogenesis.

I used to contribute regularly to Wikipedia and spent many hours editing articles each week.

The deletionists ended that.

Too much of my work was being deleted for stupid, arbitrary reasons.

If someone is willing to spend hours writing an article about Trudaeu's son, then it's reasonable to assume others are interested in reading it. Even if no one reads it, it does no harm by existing.

The deletions need to stop.

Who?

... a new term to describe such people. The malamanteu: wikanon.

If you can't handle a less than 15% change in one stock for one day you have no business looking at individual stocks.

Any of their users bet on that happening, and did they get their winnings stolen? :-)

Also smart contract defined tokens may allow tokens to be frozen per the terms of the contract.

Some chains allow freezing specific transactions. It may or may not require a consensus of validators. It's rather controversial among crypto enthusiasts.

Not your keys, not.your crypto.

... the markets got into trouble in 2007-2009. CDOs and CDSs became "artificial" and it became possible to go long or short a security that really didn't exist. Add that to the creation of "naked" credit default swaps (CDS) and more money was being bet (in the end, shorted) on things than the face value of the things themselves. Naked CDSs are pretty much gamblers bets. Because you aren't buying them to protect an asset that you have. And gambling commissions are much better placed to keep an eye on such markets. And whether a game gets thrown if too many bets are placed against it.

It's like me (and all your other neighbors) buying fire insurance on your house. When there's more money to be made by your house burning down, the invisible hand of the market moves so as to make that happen.

I think a more accurate description would be "Canada agrees to pay to access EU Network of Supercomputers".

Don't Google that on the family or work PC. :-)
