Hi @ononiwujoel,

Sorry for answer late.

UPVU service works like below:

1 . Delegate SP
If you delegate SP to @upvu, there are two benefits.
At first, if you posts, @upvu will upvote the post once a day(based in Korea Time, UTC +9, First posting).
Another is you will receive STEEM or UPVU (Steem Engin Token).

2 . Transfer STEEM
If you transfer STEEM to @upvu, you will receive UPVU from @upvu in a few minutes. 1 STEEM = 1 UPVU

3 . How to exchange UPVU for STEEM
Just transfer UPVU to @upvu. You will receive STEEM after Min 1 week, Max 4 weeks.

UPVU APY around 60% currently.!!

Thanks.
