What blocksize is the best in terms of getting fast and stake? I had a lot of small blocks <30 which didnt stake after 17+ days - also has eaten 30% of my i5 cpu . So I cleaned my wallet up and made 10 x 5k blocks. These stake pretty much within 12h of being 10 days old. I just took a look in the wiki and I'm not sure what the slows the rate coins are generated means? What blocksize you guys prefer and why(explain as I'm 5 years old

)? I'm kinda not looking through here.
Benefits of larger blocks:
Larger reward on PoS generation
Lowers the CPU use to run stake (multiple small blocks are more difficult to process)
Faster generation of stake (wastes less power running computers)
Benefits of smaller blocks:
Enhances network security (more hash rate devoted to PoS)
Easier for the network to process
Slows the rate new coins are generated
You seem to have figured it out pretty well yourself. I tend to try and keep my blocks between 3-7k. This works well for quickish staking while not hitting the max stake reward cap.
Regarding your other question, many small blocks on the network increases competition for stake raising difficulty thats means it tends to both take longer to get a stake and the reward % is lower hence slows the rAte of new coin generation.
