Congrats on being a father soon. One day, you'll be able to tell your child of the great STEEM run of 2018.
Anyway, if the belief is that SBD will continue to rise, then why sell now?
Why the hell are people selling Steem for pennies on the dollar to SBD in the first place?
I guess, the best thing to do is take the gamble now, convert your highly priced SBD into STEEM and then to Steem POWER, so you can earn more on your upvotes in the future.
