SBD has fixed total number, Steem does not. SBD value should go higher.

I'm new to SteemIt. I asking a set of questions, rather than trying to make any statement. But I'm confused about why people are surprised that SBD is valued so high compared to Steem. As of this writing SBD had spiked over $18/coin a day or so ago (now about $11-$13/coin), while Steem is about $1.5- $2.00. But SBD has fixed total coins of about 3.5million while Steem is being produced more and more thereby increasing its supply appreciably, right? If I were getting into the SteemIt ecosystem wouldn't I rather own the fixed supply of SBD?
