Only got 25% for my first stake, not to good.
PoS difficulty : 0.00042372, down from 0.00274371 yesterday. really need .0000x to get in the 40% range, you can stop minting by keeping wallet offline or using reservebalance and setting it high enough.
back up your wallet .dat before messing around.. actually back it up anyways for a safe copy "before" you need it.
I had been doing that ...
Recently, I discovered my wallet.dat file had been corrupted for several months. It was deceiving because most blocks would stake fine but some just refused. Combining blocks just made things worse as I later discovered half my wallet had 0 confirms. Scary. Rescan/salvage commands just threw up errors. I didn't want to go back too far in the back ups for fear of losing staked coins. I fixed it by extracting the private keys, building a fresh, up-to-date wallet, and importing the keys. I had some high coin age and lots of immediate staking, so the diff jump lately may partially be my fault. Long story short: Do meticulous back ups, apply updates ASAP, and keep a close eye on your wallet. Sadly, it's not a game for technically timid or faint of heart, and I certainly understand peoples' desire to keep their coins online, trading risk for ease of use. I think it may take a Google, Apple or Paypal to bring crypto wallets to the mainsteam. Sad but true. /rant
