Clixsense, Prizerebel, dollarclix, onedayrewards, are some of the sites having surveys and paying the members in bitcoin (but not only)
From this list, clixsense is a popular one wich is online since 2007 with above 7 millions members.
Clixsense has a bitcoin cashout process but it's not straightforward enough, you will get your bitcoins via tango card, you need to open a snapcard(?) wallet too. You can get your bitcoins (on tango card) into your new wallet, and from there you can send it whereever you want. For that wallet, they require you to verify your phone nr. too.
As others already mentioned, if you're not from the US, you'll get 2-3 surveys per week, $0,3 to $1 each. Tango card cashout limit is $10. It means that you have to wait nearly 10 weeks for the cashout (for $10). With a decent signature campaign (like bitmixer's
) you can do it in a few weeks with quality posts, and you'll get your bitcoins right onto your existing wallet.
