is there a mining pool for LUCK?
Yes, there are some hidden mining pools. It is difficult to detect them, because they send shares in a P2P network only between pool nodes. For example currently I can earn one block per ~40 days when solo mining and 0.001 coins per ~hour in pool. Mining on-chain blocks is getting more and more difficult, so people are sharing some easier blocks off-chain. Also, since merged mining require no additional computing power, it is profitable to both solo mine and in pool at the same time. Everyone just creates blocks as usual: if it meets on-chain difficulty, it is shared on-chain. If it meets pool difficulty (around 1000x easier now, but it depends on node settings), it is shared off-chain.
it seems you basically dont understand what the sense of luck is right ?
it whole idea behind luck is to stop mining pools. and no one exist.
that are just big guys with bunch of nodes, not more
hashrate has no big factor on luck, only node amount
