I have barely begun to post anything here due to my full-time involvement in other cash paying projects, but I have always planned to turn 50% of my payouts into Steem and 50% into SP, then convert all Steem into SBD for security. Without SBD I would convert Steem into Bitcoin and that into USDT (Tether) for the same purpose. But not everyone would know how nor be willing to take these extra steps.

Therefore, my opinion is to keep SBD to simplify securing payouts.
