First of all, congratulations on acquiring millions of steems and for this great offer.

However, at this rate your vote power will drain very swiftly, as of now it is 56%. There are lots of users who can still afford these costly upvotes and will use them to drain power in days. As other suggested and you are planning too:

1. An account similar to previous 1 SBD/5SBD-7days limit

2. Anther account with @randowhale style offer with better algorithm (research required), he is sleeping most of time these days lol

3. If possible, please make another account that can actually uplift good post with extra bonus with curating by humans or a bot with AI/ML capability (can understand languages or words), say one will send 5 sbd (that means he/she is serious about the post), if it is very good content he/she will receive 20sbd vote, if it is just OK he/she will receive minimum vote say, 8 sbd.

I did a research on types of upvote, their advantages & disadvantages, challenges surrounding them etc.
