Have started to see CGB move from balance to "stake" balance.
I had five transactions (all < 1.0 each and <1.0 total) from more than 30days ago, I got two "mining" payments this week (both <0.0x) , none of the coins moved across, but then after 34 days a 10.15 and a corresponding 0.09938 "mining" both jumped across to the "stake" balance.
Will be watching to see how the remainder of the coins go - just one question, is there a new block 'mined' for the 10.15 'stake' and would I be correct to assume unlike the 10, 5, 2.5, 1.25 payouts, this block netted the 0.09938

That was yesterday - today the whole balance is back to the "balance" with zero in the "stake" - is this right?
One last question, is the fractions only to six decimal places?
Thanks,
In your client click on,
help- debug window- console, then type in
listaddressgroupings. This will give you a list of every address used by your client to store your funds.
Each address and balance qualifies for stake separately after 30 days. This is why it may seem like random amounts are being held as stake.
I also use this action if I need to send some funds, so not to disturb multiple addresses which your client probably will do if done the normal way.
I
listaddressgroupings then I choose an address from the list, type -
sendfrom <theaddresschosen> <theaddressI'msendingto> <amount>.
Many thanks to the people who've taken the time to reply - I appreciate your feedback.
I was already aware of the eight decimal laces, however, my CGB mining/ transfers have all been to six decimal places (the whole lot) so I wasn't sure if it was some uncanny quirk or it was intentional at six decimal places.
I did the
listaddressgroupings as reccommended and got something unusual, there were two addresses listed, the first lists the balance as it is, while the second address has some "dust" in it.
Now I have in my one wallet a couple of addresses 5a... 5b... 5c... and 5d... - only this one found in the
listaddressgroupings is a 5z... Still not sure how that happened, but hey, more coins is good right?
(5a was created with the wallet, 5b is to transfer from ConEx.PW 5c is a public donation address and 5d is a spare address) - where 5z fits in I have no idea...
