Hi there Alexander64 ,
Welcome to Steemit ! I am @minnowhelp, nice to meet you !

I do check the values of some offers here and hope so to help new steemians. I just started this project !

In my session 1 of testing the value of an @booster upvote I tracked the gains of different users by using this offer - so - for example @mahdiyari got for an investment of $1.96 and Post Upvote worth $5.08 !

if you want to save money, follow me on my blog! :)
