We have many layers to our Canna project.

Firstly you can follow our curation trail (@Canna-curate) for a small upvote from @Canna-curate and from the @Canna-Collective account

For a bigger upvote from Canna-Collective you can buy some CANNA tokens.
For a bigger upvote from Canna-Curate you can delegate some STEEM Power to that account.

I am now also following the curation trail @ 3% upvote so anything that is curated by the Canna-Curate account gets a bonus vote here.
Being a VIP entitles you to a much bigger upvote from one of the two accounts (or both) in addition to the MASSIVE vote from this account.

TLDR; join Canna-Curate
