Is the reward variable and the difficulty? What's the maximum amount of coisn to mine? Maximum block size?
Why are you asking? According to your posts, you think the blockchain and the corresponding coins are just nonsense of nerds who are not familiar with economy and finance. Do you just want to gamble?
The problem with crypto currencies is not blockchain technology, the problem are the gamblers.
Admittedly, some computer freaks neglect the economic aspect. But wasn't it the same in the dotcom era? Most companies of the dotcom era failed, but those that are left are currently dominating the economy. I have experienced this time and much in blockchain/DLT development is like a Déjà vu for me.
Nerds were not to blame for the financial crisis in 2008, but gamblers who call themselves investment bankers.
For example, we are planning to implement blockchain-based fund raising for non-blockchain SMEs, as we see potential there. There are already successful examples of this in Singapore.
We use master nodes to leverage investments, but we look of course at the underlying projects. In this way we create a win-win situation for all sides.
Therefore QRK is exciting for us and we see a lot of potential, but unfortunately the developers are a bit slowly in fixing problems and communication.
