SBD is fundamentally different from stable coins. Stable coins need to have a consistent value, i.e. they are STABLE. Although that was the intent with SBD, and it has a floor value, its price history clearly shows that it is not a STABLE coin.
I wouldn’t trust Tether, and I am hesitant with other stable coins like USDC or True USD. The best bets are trading for actual $ where possible, or bitUSD, mostly on the Bitshares dex.
If Binance was framing this as pick your stable coin, USDC or SBD, frankly that was disingenuous. They are apples and oranges.
The purpose of a stable coin is for price predictability, for the purpose of asset protection/retention or trading. Sure, SBD is a great buy when its value is close to 1$, because you protect your assets with a good chance of significant appreciation. It is a much different story once SBD shoots up to $30. Now your floor represents a 96.67% loss.
