The "Boost" feature of #Ecency makes @ecency upvote your chosen post by the amount displayed on the form (but actual vote worth is less than what is displayed, according to my experience). For example, if you request that your post be voted using 500 Ecency Points, you will see that your post will be upvoted by about $1.790, but you will receive only a bit above $1. 💰🤔

The "Promote" feature promotes your post as an untargeted advertisement across the Ecency platform, randomly mixed with other Ecency users who promoted their post (or others' posts). 📢🤔
