How are you making profit if you are giving 100% refback? How did you make 100k with a "paid to" site? How popular was it and how many daily visitors and members? Why do you no longer run it? You could run a "paid to" site and retire on that kind of profit if you stick it into a good investment.
How does covering user withdraws enable freebitco.in to turn a profit?
I didnt make $100k, I made a percentage of that and gave out $100k+ in payments. It was the earliest bitcoin 'paid to' website. Surveys and stuff. I no longer run it because the hosting company who owned the software which ran it, lost it in a server migration...and they didnt have a backup! luckily I had paid my customers beforehand and no customers lost any/much income. I had over 20k members.
Oh ok. So is doing this worth it? You making a good profit? It sounds like a good idea to keep people active which is what you need. Having 1000 active refs looks good. I see the recent pay was like 24k satoshi. That is every day just for doing nothing. I think 10k refs will be a good place to be making you 240k satoshi. I wonder how long it will take to reach there. I am very interested in learning how others make money so I can take what I learn and apply it to my own stuff.
