What moved

The largest coins, a plain Ethereum transfer, the Hacker News front page, and repositories created this week. The whole market is on pulse. No account.

About this desk

What you use it for
Open this in the morning for movers, the cost of a plain ether transfer, Hacker News, and repositories from the week.
What the numbers are
Gainers are coins up on the day. Losers are coins actually down, not the smallest gains. Gas is a plain Ethereum transfer. Posts and repos are the public items those sources returned.
What it leaves out
The mover lists are a slice, not every coin. A source that misses is named. This is not the full news wire.

Every desk is introduced the same way on the desk list.

How to read this

Up and down
These are the five largest moves inside the 24 coins this page loaded. The percent is versus that coin's own price a day ago. It is not a ranking of the whole market.
A simple send
$0.019154 is 21,000 gas at the average quote of 0.34 gwei, times the ETH price. 21,000 is the minimum for sending ETH itself. A token send uses more gas, so type that size on the gas desk before you treat this dollar figure as the fee.
Points and stars
Hacker News points are votes on that story. Comments are replies. GitHub stars on the new repos are bookmarks. None of them says the story or the code is correct.
