I agree except that I'd like to point out that SBD spiked because it was introduced at exchanges for the first time. The USD peg only acts as a floor for the price of SBD. It was clearly in overvalued territory after the spike but SBD actually has a stronger value proposition than almost any cryptocurrency out there.

One regret of mine concerning November/December 2017 was not realizing that SBD was a pretty good stablecoin for profit taking prior to the spike. I was apprehensive about buying USDT because of all the FUD but I was loathe to buy fiat because of taxes. Partial profit taking in November just before the introduction SBD on exchanges would've resulted in an incredible windfall. :D
