That is correct and if you read the post more carefully maybe you will realize I didn't make a mistake :D
The only thing about it is that 18% annually with interest compounded on a daily basis turns out to be somewhere in the range of 19-20% APR.
2% is just the reward we get for hodling SP.
And where does the 18 % comes from ? Delegation ?
Exactly!
yes, but when you delegate your SP, then you are loosing the fun to upvote. So you need 2 accounts, one to save and one to play. :)
I added a link to your post at coinschedule on the steem forum https://www.coinschedule.com/cryptocurrency/steem
Or you can delegate only half of your SP and upvote with what's left :D
Thank you!
