I believe that everyone should buy as much SP as they can BUT consider this though!

What if I told you that you get more SP with the 50/50 option?

Let me explain...

STEEM is currently trading at aproximetly $3.00

Let say you get $15 from the post.

If you choose to power up 100% option:

$15 (payout) / $3 (current STEEM value) = 5 SP

If you choose 50/50:

You'll receive 7.5 SBD + 2.5 SP

SBD is currently worth $2.4 (you can check the current price here:

7.5 SBD x $2.4 = so you'll get $18

$18 / $3 = you'll get 6 STEEM and power up = 6 SP

6 SP + 2.5 SP = 8.5 SP

So with one you would prefer ?

100% = 5 SP or 50/50 = 8.5 SP

Thanks to @shenanigator and his post and comments I never choose 100% unless the SBD is trading below $1.00
