that link really needs updating - there are parts that are no longer working - the first exchange has no volume to buy DMD and the pool it lists as being able to mine btc and convert to DMD is down.
it states there is no limit required to receive staking rewards, only that if you have less than 1,000 it wont be daily - is that still correct/valid?
We are all waiting for the transition to V4 which according to Cryptonit will take place in a few months.
Therefore, I do not see any point in updating any information there, especially since it is still relevant today.
The trading volume is currently minimal because the Livecoin wallet is undergoing a resynchronization process.
There are no minimum limits on the number of coins for POS betting.
But if you want to find about one block per day, you need to have at least 1000 DMD.
