I used coinsmarkets.com and for staking and am getting stakes much quicker. Before it took me almost 2 weeks in my own personal wallet but I the pooling of B3 in coinsmarkets does help. I am making much more in stakes and more frequently.
If anyone here isn't making stakes often, like every 2 days then I suggest pooling your B3 in the sites wallets. I deposited and withdrew with no issues.
What is the overall number of coins being staked in the pool?
Todays B3 Stake distribution was 10,600 B3 so the total must be over 80,000 B3. Maybe even over 200K B3.
What do you mean Today's B3 Stake? According to the Stake overview the last Stake was at 09/26/2017 08:09:07. So that stake was probably for many days, meaning the amount of coins in the pool is a lot lower.
