I think people misunderstand how NH works. You are not "mining the most profitable coin" - your coin profits don't come from mining, they come from people paying you to mine for them. The reason why the algos might be disappearing is that there aren't enough buyers in the market to make it worth NH's time to keep the miner in. I think it's sleazy myself but I feel like if they're selling on the website, they should be buying on the software.
