I think Ripple will be the way to go. Fortunatly I don't have any pending ETH transaction right now, but it stressed me out when it took 30 mins to make one. People that are new to crypto, don't want to learn all about how gas fees work etc, at least most of them, so this is not ideal. And I think you are just forseeing the future bitcoin crash with this news, actually I didn't knew steam was even accepting it lol. But yea if it already started happening, it will lose popularity, as other cryptos become more mainstream.
Will sbd's go down in price again? What if they don't?
SBD will go down in price. It will just take time. The blockchain should be putting extra SBD out to people for rewards to try to lower the price. It is supply and demand though. There is not a lot of SBD supply, but there is a ton of demand. This has caused the price to skyrocket.
There is a bunch of demand for Steem right now, as you saw by the pump, but there is WAY more steem than SBD. Which is why Steem did not climb even close to as high as SBD did.
