Review of some free btc sites

1. bitcoinget
Started off great, had nice payouts to watch videos, and a decent number of videos. As price of BTC went up, they were relatively quick to lower payouts. During one conversation with the admin he claimed to try to have a payout equiv of about US$ 0.005 per video. Recently they added "tasks" but they seem pretty stagnant (which is out of bitcoinget's control).
Currently pays 32 ubtc ( 0.000032) per video, but it's extremely rare for me to get a video anymore (although I have a friend that usually sees several videos when he logs in).
Used to pay out several times a day, now I'm not sure because I don't get enough videos to know.

2. free.btc.pt
Started out (imho) subpar to bitcoinget, but has improved alot. As price of BTC went up, they were relatively slow to lower payouts. Recently added a referral program. They also pay 100 satoshi (0.000001) per hour you are logged in (I remember it being 1000 when I started). They currently pay 4000 satoshi (0.00004) per video. Also you can solve captcha's for 50 satoshi (0.0000005) each. Another service they have is called "satoshi millions" which is the old do survey, download (potential) malware for btc. Now it appears that to even use this feature you have to publish it via google+ or twitter.
As you can see, not only do you make a tiny amount to just leave your browser open, it pays more per video than bitcoinget.
Payout is slow, after you "request" a payout, it usually takes 24-48 hours to receive the payout. If you have a referral, every time they request a payout, you receive 10% of their payout into your account immediately.

3. dailybitcoin
In my opinion, this site and coinad have been fighting for my preference. Right now they are on top. Once an hour you can get a payout, with a minimum payout of 0.00001, with some luck you can get 0.00005, and there is a maximum payout of 0.001. In order to request a payout, you must now have 10x minimum payouts or 0.0001. They were relatively quick to lower payouts as BTC went up in value, but also pretty quick to bring the payouts back up. Has a unique feature of the chance of getting peerbet credits on some payouts of 0.00005.
Right now the site claims to have 307 payouts per day of 0.00005.
After you request a payout, you usually receive it within 24 hours.

4. coinad
I used to feel it was better than dailybitcoin, but imho it's gone downhill. They were slower than dailybitcoin to lower payouts, had a way to get btc from doing "work" (the usual do a survey, or download (potential) malware), but this has been discontinued (no loss IMHO). Right now the hourly payout is 0.00001 with no chance at a higher payout.
Relatively new feature (couple months) is to chat for btc. Currently there is a payout chance of 25% per time you hit enter, with a payout of 0.000001 btc, but in my experience, your chances are much lower than the claimed 25%, and from what I can see, the "chat" has lowered to people almost always just entering jibberish to get that tiny reward.
In my opinion, they should increase the chance of payout from chat, but drastically lower the payout amount. They also need to bring back the chance of getting a higher hourly payout.

5. bitvisitor
This site you view an ad for 5 minutes and get a payout. Lately the payouts to view are (8 ubtc) 0.000008 btc to (88 ubtc) 0.000088, with payouts closer to 8 ubtc being more common. Tends to have a decent amount of ads to watch.
As far as I can tell, payouts now happen many times a day (maybe hourly?).

6. earnfreebitcoin
Used to be a good site, but it's performance is pretty week now. Last time that I went there, they claimed "Earn up to 32.08 (0.00003208 btc) ubtc per day or more". That statement is a pet peeve of mine. How can you earn "up to" or "more". Additionally, 32.08 ubtc per day is horrible.

7. bunnyrun
This is a unique once per day site, payouts are 0.004 mbtc (0.000004), 0.006 mbtc (0.000006), or 0.01 mbtc (0.00001) based on how you do picking the fastest bunny during a race. The payout per day isn't great, but at least it's unique and somewhat entertaining.

There are several other sites to earn btc (virtual faucet, el bitcoin gratis, can has bitcoin, netlookup), but imho, I listed the main ones. I didn't list the actual websites, if you want those, google is your friend. I spent the time to equalize payouts in BTC as many sites show payouts as BTC, mBTC, uBTC, or even satoshi; this is to make it easier to see which fits your needs based on time and payout. I sure would be easier if they would all just standardize on 1 unit to make life easier for us freebiers lol.

I wish everyone the best of luck with these and other sites. If you like what I've done, consider tipping me at the address in my sig below.
