I don’t really know if anyone has tried this before, but I just submitted a change request on Coinmarketcap to remove the marking/label on the https://coinmarketcap.com/currencies/cardano/ page as it being Mineable.
I wonder if they’ll even look into it, and wonder why it still hasn’t been removed. No one else has either never send a request (which seems unlikely) or they simply don’t handle their feedback well?
Currently Cardano runs as federated system, all current nodes (aka pools) where in control of IOHK (maybe also Emurgo and the CF, but I’m not sure about that)
There are several papers for all the different Ouroboros “flavours” and they are all basically proof of stake, but of course you are right: at the moment you can not stake your ADA. Best way to think of it is that everything is defined static.
It runs with Ouroboros Classic protocol between 7 federated pools. It is technically PoS, you just can’t participate with your own pool/stake currently.
It’s probably the accumulated given coins out of the chain to holders from the master node (nodes?) themselves. After releasing the coins you can only track what you gave and not what is where anymore.
If you didn’t get yet that Cardano is in federated state currently and staking would be live when Shelley is released, maybe and just maybe Cardno isn’t for you!
But at least, at this stage of the project, you own some ADA whisch make you somehow a visionary
