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.
