STEEM and SBD are never burned. The witnesses decide the ratio in which it is paid out as rewards.
If you enable 50/50 split reward on your post, you are actually getting 81% SBD anbd 19% STEEM as of right now.
This is a desperate attempt of witnesses to produce inflation and to get the price of SBD down again.
Are u sure. It looks to me like the payout is 50:50 still. assuming 1sbd = $1
Yes I am sure. Did you not notice getting way more SBD than STEEM from your posts? It used to be equal, but since two weeks ago, the payout ratio has dropped significantly. Just check your next payout on steemd.com You will see 70-90% SBD and only 30-105 STEEM paid out. It fluctuates.
The payout ratio used to be shown on steem.supply but @dragosroua removed it.
