Excellent Question….

The secret is maximum Blurt power….. Aim for at least 650,000 Blurt Power

You make the most from upvoting with your own Blurt Power. 50% APR

Next you earn the most from delegation to @jsup … 33% APR

Then next is @upvu via whalevault …. 20-30% APR …. https://blurt.upvu.org/

You get around 8-10% with Delegation to @beblurt or @blurtbooster

You get zero reward if you Delegate to someone who is not running a Passive Income Delegation project like @jsup @upvu @beblurt and @blurtbooster
