Same sort of mixup can happen when looking at the daily interest given, its only altogether and including compound that its 4% or higher but daily its all alot smaller but still I like that its daily; banks dont give that convenience on deposits some of them Im never sure they pay me anything as it takes forever to appear.
Daily interest is given on the "Earn BTC" page
Daily interest will be calculated at a random time everyday @ 0.0109589% per day.
However for any amount less than 100BTC invested, the daily interest would not seem withdraw-worthy. I would rather run it for a month or a year before I withdraw.
What about 10BTC investment? It generates 0.001BTC daily that is equal of $37 daily or 1200 USD monthly. It's more than enough income for those who live in poor countries and still a very good addition for those who live in rich western countries.
