Thank you very much for your enthusiastic explaination. However, there are many coins now running POS and it seems that their mechanism is similar to that of ADA. Do you think I am right ?
DeepOnion has staking, too. I am running the wallet all the time and I staked so far hundreds of coins.
By the way, Callisto Network has Cold Staking, which means the staker lock the coins in an escrow and passively recieve an interest shared from miners.
