1) I can't vote either.
2) "expected time to earn reward is 4 hours" - It's said that for 2 days. 5 days ago it said 10 hrs so its making progress. What's up with this? I've had my XBC for a week with no staking.
BTW I'm a big fan of this coin, I think it has a huge future, I just don't understand the staking discrepancy.
From what I've seen the time estimation underestimates how long it will take. In any case, it is probability based so will vary but decrease over time until you find a stake. It seems like the discrepancy could be based on estimating the time to stake based on a fixed estimate for block generation rate which is faster than what the network has historically shown. I'm not really sure if this is due to lack of transactions or lack of weight relative to total possible weight (because of offline wallets). It would be nice to hear an explanation. In any case, this phenomenon is not unique to XBC, I have noticed it among most proof of stake coins. XBC is very stable and problem-free though. I am always running it and never have problems with connections/database integrity, etc. Only in the case of improper shutdowns have I had to reindex.
