What I would like to know is what benefit Steem holders get from SBD?

Real users!

In past two weeks, two my friends which I invited to platform did a favor for me, which require from them to spent money.

Both of them were never before crypto-users. They have a steemit acccounts, but they do not use it very often. When I asked them how they want to be compensated, answer was:

SBD is a currency used among Steem community to pay for real services or goods.

This is gentle way to have all advantages of crypto (availability 24/7/365 from anywhare, speed of transaction, etc) without being exposed to price fluctuation.
