Eobot mining site does not give out free mining power but you can earn some BTC from daily faucet and used them for mining. 2 days of log in and claiming is enough to buy some mining power for 24 hours.
i didn't invested money. Only claim every day and get scrypting plan for 24 hours. It takes some time yes but it's working. Slow but safe and stable money.
Now here's the step to earn btc without investing real money :
1. First register on link in posted thread.
2. Login and go to "Products" -> "Faucet".
3. Type captcha and earn your free bitcoins.
Note: you can do that only once a day!
4. Follow step 2 and step 3 next 3 days!
5. After that you have claimed 3 times bitcoins.
6. Now your ready to start with your money bot.
7. Go to "Account" scroll down and you should see some blue menubar and choose "Exchange".
8. On the left choose your earned bitcoins(just put it all) and on the right choose "Cloud Scrypt 24 Hour Rental"
9. Now you have activated your bot for the next 24 days and you should see your earnings running in your account dashboard.
10.Under "Mining" you can switch to many currencies you will mine. I mined only bitcoins. But it's yours to decide.
11.Every day you should go to "Faucet" and claim your free bitcoins.
12.On next day after your 24 rental scrypt is over, you have earned more bitcoins. Then you should do step 7 till step 9 again...and again....and again.
13.Your collecting hashrate will rise up and you can get good money like me $10-12 per day and more.
Thanks for trust and happy mining!
Payout is low at 0.001 btcs and have no fees! and you can used any others faucet site and deposit earned btc to your eobot account to earn extra and buy more mining power

Second site is called Cryptomining Farm. This site offer free 50GH/s for new member. All you need to do is register and it should start mining. For payout or withdraw you need to to buy at least 20GH/s but you can buy these with everyday free mining. Its takes a long time but yeah you can still earn it. The Harsh power price is not too expensive. I prefer you, don't invest much money here only a small amount until you can prove your withdraw or payout cause that free forever 50GH/s is suspicious but worth trying
and also the minimum withdrawal 20GH/s need to be purchase from external wallet or from any other source. You can't buy GH/s with your balance because its still not being withdraw yet. You can watch it mining till you can afford to buy minimum withdrawal GH/s
