A really interesting idea, is it still live and going? Also are the tokens on any of the exchanges? It really might be worth to take a look if the tokens are worth something.
Absolutely alive and kicking! 994K coins mined out of a total of 21 million.
If you want to try out the mining (iQ Puzzles) the first round ones are easy. You can go straight here:
https//iqcash.net/miningBut you only start earning iQCash when you enter a Waves account address. There's info on the site about how to create a Waves address - it's pretty easy.
The only exchange you can trade it on at the moment is Waves DEX. I think we'll need to get a few more million mined before looking at other Exchange listings. This is a long term project and is getting off to great start.
