Then i guess i cannot mine the coin with my miner which is unfortunately, and what is exactly LPoS ?
I know DPoS but im not familiar with LPoS. There are already many coins created from bitcoin fork, what is the difference in this coin?
As per the whitepaper it's called Leasing PoS and the meaning of it is also there but I think I found a grammatical error on it, I bolded it on the quoted sentence below. I think that shouldn't be the meat we are expecting.

The LPoS algorithm creates a voting system that directly depends on the reputation of the validators. If the selected node does not work correctly or works inefficiently, it will be quickly deleted and replaced by another. Therefore, the validators are motivated to act honestly and effectively, so that they are further voted for with their own steak.
Question about the supply, does it mean it will be the same as the circulating supply once the BTCU launched? And when will claiming stopped? By the way a grammatical error on the whitepaper under the BTCU BLOCKCHAIN TECHNICAL SPECIFICATIONS > Coin Supply Control: it's written BTUC there instead of BTCU. Check your papers before publishing it.
