Out of those mentioned above the only thing I am doing at present is HODLING. I am a lazy person so I prefer keeping my investment at bay. I want to try trading but I am not sure if I could keep up with the process, sometimes it is really hard digest every information you see online.
Years ago I tried the FAUCET. I did get a few BTCs there but then it is so little that you can't notice the impact on your coffers

What I realize today is if you want to earn more, you need to take a risk.
