I have the same worry as you yesterday, I am afraid that the SBD price will go down after the HF19, as I see kind of the inflation here. And wondering will the big whale just down power to cash out the SBD which make the SBD become lower. But finally I still maintain the SBD, not change it to BTC, as I see the percentage of drop is not really high (compare with BTC). Of course, I wish the SBD will go higher afterware, but god knows..
