This solves the problem of Bitshares not being mineable
Correct me if I'm wrong about the concept, but aren't we talking about mining PoW chain(s) and getting paid via PoS?
One reason Bitshares isn't popular on Bitcointalk and other places compared to Ethereum and some of the alt coins is that miners seem to have been pissed off about the fact that Bitshares isn't minable. Mining is a subculture and the mining faction apparently is the king maker when it comes to marketing new coins. They seem to make up the bulk of the traders on exchanges.
So you market directly to miners by allowing them to mine for Bitshares. It simultaneously markets Bitshares on a grass roots viral level, it allows people who have all this hashing power something to use it on and then they don't need Crypsy because they can just use Bitshares. Bitshares is a decentralized exchange and people who like to trade will want Bitshares and need a way to get them.
I have a mining rig, I'm sure many people here do. So while we can mine some other coin or Bitcoin and sell it for Bitshares on Cryptsy, when we get to Cryptsy it's like the shopper who walks into a supermarket. You end up seeing all these better deals then you forget you wanted Bitshares and end up trading some other more profitable stuff.
But if your mining pool pays out in Bitshares, you're more likely to just save the Bitshares in BitGold, or trade directly in the Bitshares client. You may even be able to automate the pool so it automatically fuels your Bitshares client. This would keep a continuous steady stream of Bitshares flowing into your Bitshares client and you wouldn't have to do anything.
The mining pool could display ads, a DAC index and other information to keep people in the trading mood and by stealth advertise Bitshares. When new DACs arrive ads on these multipool sites would reach the exact demographic you want.
Correct me if I'm wrong about the concept, but aren't we talking about mining PoW chain(s) and getting paid via PoS? To answer your question. Sorta, but that is what everyone does anyway. How do you think people ended up buying the top coins on Coinmarketcap? They either mined it, or if it's Proof of Stake they have to buy it, often with profits from mining PoW chains.
This streamlines the process through automation. You just set your mining rig up and the BTS will flow into your wallet. The benefit to this is that the price of BTS wont go down because people will always be buying it. Bitshares is very hard to dump due to it's utility, but if no one tries it out no one discovers that utility.
