Hi, I don't understand this :
This means that you will want to split your HYP blocks into the appropriate amount of HYP if you want to receive 750% reward
I have a block with 10k Hyp, 49.78 Age, 11.13 Days to stake, and Priority highest and Potential Stake 1000 Hyp since a long time ; to get the 1000 Hyp I have to split my 10k Hyp another time or I just have to wait?
I don't find an answer in the wiki, so thank's for your help

There are 2 primary staking strategies for HYP, either big blocks that stakes fast(er) but give low return or small blocks that take longer but give a much higher % return.
I have a mix of both. Maybe 1/2 bigger blocks of 9-15K and the rest 3-4K. At the end of the day I think either strategy ends up close to the same result. There is still luck in staking, I have big blocks 30+ days old and small blocks that stake at 9 days.
There are some using jumbo blocks over 25K but David Suzuki believes jumbo blocks are contributing to coral bleaching off the coasts of Australia and throughout the South Pacific so I wouldn't play that game.
