First don't use minnowbooster to make profit, use it to promote content.
Second don't get confused by the fact that 1$ as displayed by steemit is assuming that SBD is pegged to USD. Your post reward for this post will be
2.48 /2 * current-SBD-rate in STEEM, or about 1.24 USD worth of STEEM/SP
plus 2.48/2 SBD, or a little more of 5 USD worth of SBD
Thank you I did not know it was pegged to the dollar makes sense now why I profit the value in Steem and not the value of BTC spent on the 1 SBD
