That is very true! The SBD price does pull the Steem price up as well, and the SBD posting rewards give a huge incentive for new bloggers/vloggers/developers to come and join the platform.
This SBD price increase is a blessing to Steem as it raises awareness about the platform, and creates a snowball effect of positive growth on the platform.
What Steem really needs ASAP is more Steem/SBD/fiat gateways, as well as some kind of 2FA security feature. Just my opinion.
