Today my wallet crashed again. I was Encrypting it, and after putting password it closed. When trying to open wallet again, it crashed. Sent all the files to replace, from pendrive, but also put wallet.dat without realizing (wallet.dat file pryor to encryption)
Now it works but is not encrypted. Wasn't supposed that that file would not work or asked for password? (I think i did read that while encrypting wallet)

In regards to staking, is it the same having one big transaction or several smaller? (with total value being the same)

Glad that you sorted your problem, Anotherlateminer
