PS Personally I think Steem value will go to $100 with SBD at $1 only.
I doubt that! We must weigh the total supply of steem compared to sbd. You can't leave sbd $1 and wanting steem to go $100 with so much steem supply. the reason why sbd surges up because nobody stacking sbd. You can look up it's total supply less compared to steem.
USDT (Tether) at $1 to be 'cheap', or 'a buying opportunity'?
IMO. tether will always be pegged to $1, They can simply issue tether and reissue again without informing us. Compared to sbd, With limited supply and can be created "only" via post rewards.
