SBD I think is useful for trading purposes. As a novice in crypto trading I have been observing for a few weeks everyday that people trade tether a lot in hopes to retain the USD value without going through the ups and downs of crypto. SBD was suppose to function the same but demand for it has recently lifted its prices. If SBD is pegged to the USD for good it will likely be a better alternative than tether. That is because the steemit blockchain is the collateral of SBD. There is still a lot of unknowns regarding tether. Like rumors bitfinex created it and uses it to jack up crypto prices. I can not say for sure but a lot of people have done research on it.

For now a lot of users are pulling their SBD and converting them to USDT or other cryptos because of its unnatural higher worth. In the end SBD is suppose to fall back to equal the USD. So people are taking advantage of the situation as we speak. For red fishes like me who does not trade a lot I would go to the "currency market" and exchange my SBD for steem. Note right now you can still get around 2.5 steems for every 1 SBD. Your account value on steemit will increase ~250% for ever SBD you convert into steem. As a die hard follower of steemit why wouldn't I want to do this? Thanks.
