I don't tell you that you get rich by doing this but I assure that it's not bad if you have nothing to do.
BTW: You don't have to invest anything to begin.
https://freebitco.in/?r=24276718 is a website that many already know. If you don't know it : It's a site containing a bitcoin faucet and gambling service.
To make some money there are only a bit more than 10 steps.
I made these steps/rules based on my experience with this site(It's important to read the entire post).

• Get yourself a balance of about 0.00001000 BTC by claiming the faucet every hour.
• Go to the Multiply BTC section
• Bet the minimum amount on either HI or LOuntil you have either won 4 times in a row or lost 4 times in a row.
• If you have won for 4times in a row increase your bet to 0.00000010 BTCand bet on the other side.
• If you have lost for 4 times in a row also increase your bet to 0.00000010 BTCbut bet on the same side.
• After winning return to the base bet.
• Everytime you lose after winning 4 times or losing 4 times double your bet butand this might be the most important thing to remember... Don't double your bet to often because ,although it is not very likely, it can and will happen that HI or LOwins/loses more than 4 times in a row.
• Because of this you should only double your bet for 3 or 4 times(maximum).
• Keep this in mind and losing all your money will be very difficult.
• After reaching a higher amount like 0.00010000 BTCyou can increase your main bet (as i call it) from 0.00000010 BTCto something like 0.00000020 BTCand so on.
• Continue following steps 3-11 and don't forget to claim your free BTC in the free BTC section.

Example : Bet amount = 0.00000001BTC
LO - lost
LO - win
LO - win
LO - win
LO - win
Bet amount = 0.00000010 BTC
HI - lost
Bet amount = 0.00000020 BTC
HI - win
Repeat
Explanation : After betting on LO for 4 times and winning the probability of winning for a fifth time is only a bit more than 5%.
