It found a new floor, and they've since rebuilt and added to their team. Development and communication channels are active.
This update caused the spike you see that has since retraced a good bit: https://medium.com/the-quantum-resistant...
Their mainnet (it's currently an ERC-20 token) is due in Sept/Oct, and if it goes well it offers real upside for this token.
With risks of quantum computers, QRL could prove an interesting test bed for resistant features that could later be soft-forked into other coins.
I don't think this will take over the world, but it's a good project, and I think still oversold. 12.6k sats looks like a good entry. 10k sats looks even better. 20k sats seems like a reasonable target, with more upside based on how their mainnet launch goes.
