You havn't even listed all the free ones.
Which ones?
Look for yourself, there are plenty.
I did of course. Perhaps English isn't your main language and you aren't clear on the
difference between "free" and concepts like "earn" etc.

"surf these websites...
fill out these surveys...
give me your email address and personal information...
watch these videos...
reweet or post these ads...
build me a house...
AND I WILL GIVE YOU FREE MONEY!"
LOL
Even if it is only time and attention someone wants it is still valuable to me
and anything I get in return for it, should I choose to spend it, isn't free.
Now if the only time I have to spend is the time it takes to load up a website
and input a bitcoin address, and maybe wait a few seconds for some anti-bot
process or the like, and anything else is optional then I can regard any bitcoins
given out in that case as being reasonably free.
