i think the dev should give an explanation to the 10⁽-⁴⁾ shown on the nano wallet  mathematically it is incorrect if it represents the % score.
must be 10⁽-²⁾

Supernode Total: was 629, now 631 Nodes (Active:454)

The arse will fall out of it at some point soon. This is nothing to do with fundamentals or news, though they're improving all the time for NEM.

In case you hadn't noticed every coin is pumping. Some of them will be good. Some will be utter shit. Most of them are no different to how they were a month or two back other than a bonkers price. No direction lasts forever.

Is there a historical chart that shows active supernodes at any given time?

supernodes.nem.io only seems to have total nodes, but no easy way to spot all active ones without weeding through the list.

Xarcade is a NEM powered video game distribution/exchange platform for both game publishers and gamers to use and is a more direct alternative to the other app stores.  The video games on the Xarcade platform will all have NEM wallets built-in whereby the gamers can exchange XEM for the in-game tokens and vice versa.
What makes Xarcade unique is that the gamers using Xarcade will be able to exchange the XEM they make for real money.  Thus, Xarcade is providing games a fun and alternative way to make generate income.

The advantages that a NEM powered blockchain video game distribution/exchange platform brings:

Below is a YouTube video of an indie game publisher called "Xhai Studios" that has signed up to Xarcade and has "NEMified" their endless runner mobile game known as "Send 'em to Hell."

•   It reduces the in-app fees for the game publishers by creating a direct exchange relationship with their users (the gamers).

•   Gamers can now exchange in-game currencies both ways, which they are unable to do before.

•   No need for a linked credit card for in-app purchases, so one has faster transferring.

•   Some countries do not have the Google Wallet or the Apple Pay feature available – blockchain allows for this.

•   Google and Apple each take 30% of the revenue from the game publishers – this does not happen on.

•   Blockchaining video games creates a disintermediates the established “middle men (the app stores)” and creates a direct relationship between the game publisher and gamer.

•   It allows the game publishers to rely less on generating revenue from advertisements, which annoy the gamers usually and to make more revenue from in-app purchases since Xarcade would take far less than 30%.

•   Xarcade allows the gamer to make income because the in-game currencies of various games can be converted into XEM, which in turn can be converted to real fiat money.

•   The blockchain API’s will allow games on the platform to interact directly with one another using “blockchain nodes,” which in-turn will make any third party middleware irrelevant.

How Xarcade Works:

•   A game publisher and gamer both sign up to the platform in order to upload and manage their games.

•   A gamer signs up to the platform in order become part of the gaming ecosystem whereby he/she can exchange cross-platform in-game tokens.

•   A game publisher can directly distribute their games in a much more cost-effective way as well as removing the “middlemen” entirely.

•   All platform transactions will be verified and processed using NEM blockchain technology in a safe and secure manner.

•   Gamers will be able to make in-game purchases and be able to convert game points (tokens) into NEM’s cryptocurrency called, “XEM.”

•   The XEM conversion not only incentivizes gamers to keep playing but also provides players with the opportunity to earn extra income by playing games.

•   All games uploaded onto the platform will include a built-in “XEM wallet” with QR code functionality which will allow gamers to exchange XEM with fellow gamers.

•   Gamers will able to convert their gaming points from XEM into Bitcoin or fiat currency.

•   The XEM wallet will be available for download from the platform in order for the game publisher to integrate it into their games.
•   NEM’s API will allow games on the platform to interact directly with one another using blockchain nodes, which in turn will make any third party middleware irrelevant.
