Signature campaigns and Digibytes are your best options.
Hello, can u explain to me what Digibytes are?
I am interested in earning much, I have much free time today.
DigiByte is an alt coin. You can earn Digibytes by playing CS:GO and LOL. They do have a thread in here -->
https://bitcointalk.org/index.php?topic=408268.0, you might want to check that out to have a detailed information. Since you mentioned that you have "much free time" today, spend that time to go deeper and learn how you would earn DigiBytes.
Another way to earn more is to get your friends verified with digibytes, basically the way to do that is to get your friend's to paste a random thing the digibytes website gives into their mastery page and save it and wait for a couple of seconds. This way you could do other stuff while they enjoy playing and you earn more.
